Hello.
0:12
I'm Dave Jackson, the Senior Manager of Application
0:15
Scientists for HID here in North America.
0:19
You might remember me from HID's 2022
0:21
when I took you on a tour of our pleasantant site
0:24
and introduced you to the then new HID Nimbus Presto automated
0:29
purification system.
0:31
And that was wonderful to do with you back then.
0:34
Picking up where we left off in those flashback videos,
0:36
I'm pleased to share with you additional capabilities
0:39
that Han mentioned back in 2022.
0:42
That is the addition of automated quantitation
0:45
setup, normalization, and amplification setup
0:48
all in the one instrument.
0:50
And that is the HID Nimbus Presto QNA.
0:55
With this instrument, labs can save valuable time,
0:58
experience consistency from sample to sample and analyst
1:01
to analyst, and benefit from the quality and support
1:04
that they've come to expect from thermofisher scientific
1:08
throughout many years.
1:11
Now, this session has been recorded
1:13
prior to the release of the instrument itself.
1:16
And not many people have seen the instrument in action.
1:20
And I get the privilege of being the person
1:22
to unveil the HID Nimbus Presto QNA to one of our North
1:27
America customer labs so that they can hear firsthand
1:31
how it works, and I can glean from them
1:35
their initial impressions.
1:36
And so with that in mind, I'm really pleased to introduce
1:40
to you two of the criminalists from the San Mateo County
1:45
Sheriff's Office Crime Laboratory,
1:48
Matt Cindy and Kimberly.
1:50
Welcome Cindy and Kimberly.
1:52
It's great to have you with me.
1:53
Thank you for having us.
1:55
Cindy, I wonder if, first of all,
1:56
you can just tell me a little of your history of why
2:00
and how long you've been at the crime lab there in San Mateo.
2:05
I have been with the San Mateo County Sheriff's Office
2:08
for 24 years now.
2:10
I am a senior DNA criminalist, and I
2:14
have full response to crime scenes.
2:16
And we are looking forward to having our Nimbus Presto up
2:19
and running.
2:20
So a lot of experience in all of your years there
2:22
with the crime lab in San Mateo.
2:24
I'm really grateful for you joining me today.
2:27
And I'm very excited to show you that.
2:29
Kimberly, it's good to see you two.
2:32
Welcome.
2:32
Thank you, Dave.
2:34
We've gone back a long way, but I
2:35
wonder for everybody's sake if you would let me know a little
2:38
of your history, where you've come from,
2:41
and what you're looking forward to today.
2:43
Sure.
2:44
I have been with the crime lab here for almost four years
2:49
prior to coming to San Mateo crime lab.
2:52
I was a DNA analyst at the San Francisco Police
2:57
Department Crime Lab, which is where Dave and I met
3:01
for the first time.
3:03
And both there and here I am a--
3:07
like Cindy, a senior criminalist as well in the DNA units
3:11
and also respond to crime scenes.
3:14
Great.
3:15
Well, again, ladies, thank you very much for joining me today.
3:18
Wonder before I get started with showing you
3:22
what is capable through our new instrument.
3:26
If I could ask you just a couple of things first
3:28
about your workflow in your lab situation, perhaps, first
3:33
of all, you could let me know what some of the pains or bottlenecks
3:37
are that you experience in your case workflow.
3:42
I can go first.
3:44
We only have four criminalists who are trained and able to do
3:52
sexual assault kit DNA testing at this time.
3:56
So sexual assault kits, as we all know,
3:58
take a lot of time and energy and it is our bottleneck.
4:03
We can only do a certain number of samples in a batch.
4:07
We pretty much do everything by hand
4:09
except for the actual extraction and digest.
4:13
Thank you.
4:14
I guess that should take-- or it does take you quite a bit of time
4:17
to do all of that manual processing of your samples.
4:20
Yeah.
4:21
And I'll also add we are doing a lot of manual pipetting.
4:26
I mean, if we don't have heart threats now,
4:29
we might have it later.
4:30
So preparing a 96-well quant plate
4:35
or normalizing our samples manually and again,
4:40
preparing another 96-well plate for those two steps
4:45
in the DNA analysis process.
4:47
And those just itself take so much time
4:53
versus working soon, hopefully, with a robotics liquid handling
4:59
instrument that can take that time away from us.
5:03
We can focus on other things, like finishing writing a report
5:08
or interpreting data for a different case.
5:10
So that is definitely what I look forward to
5:14
is the ability for this instrument to help us multitask
5:20
and work on something else that needs our analysts' eyes
5:28
while the instrument is at the same time running samples for us.
5:33
So I look forward to that so much.
5:37
And so does my wrists at hand.
5:41
Madge and Kimberly, I can imagine.
5:42
And you've gotten right to the crux of the issue.
5:45
There really is the time savings that an instrument like this
5:48
can provide to you.
5:50
Cindy, are there any other thoughts about what you might want
5:52
to use the rest of your saved time for within the work
5:57
and the duties that you have in your crime life?
5:59
When we have the robotic online, it will save us a lot of stress,
6:05
really.
6:06
That's what I'm looking forward to,
6:08
because we'd be able to do so many more samples,
6:12
not have the physical difficulty of manual labor.
6:15
I can imagine that makes a big difference for sure.
6:18
When you use on software, how important is that software
6:23
interface to the work that you're doing in the various
6:26
workflows within your laboratory?
6:29
I can go first, because I am not.
6:32
Anybody good to ask you, I am not computer savvy at all.
6:36
So it needs to be pressed this button, then this button.
6:41
There it is, print.
6:42
That's how simple I need it to be.
6:45
I want to spend my time on the cases, like what I'm here to do.
6:51
I'm here to work these cases, to evaluate the data, write the
6:56
report, test of phy in court, help with training.
7:01
So an easiest software for me is, oh my gosh, I love it.
7:07
OK, that's great to hear.
7:08
What about you, Cindy?
7:10
You know, I just think we should utilize technology for what
7:14
it can do.
7:15
We have been stuck in the dark ages using Excel, spreadsheets,
7:20
and then exporting that data.
7:22
And that's so 20 years ago.
7:24
So why aren't we utilizing technology to make things easier
7:27
for us so that we can focus to the core of our job, which is
7:31
analyzing evidence to develop DNA profiles?
7:36
Wonderful.
7:36
Well, listen, again, I'm so pleased you're with me today,
7:39
because what I want to show you is perhaps something that will
7:43
address those concerns, those time-saving efforts, those
7:47
plug-and-play software topics that you brought up,
7:50
Kimberly as well, all contained within the HIV
7:55
Nimbus Presto Q&A system, which really does offer efficient
7:59
purification of nucleic acids from laced samples, automated
8:04
quant and amplification set up, as well as the automatic
8:08
normalization of your DNA samples as well.
8:11
And it's specifically scripted and optimized and validated
8:17
with our that being applied by systems, industry-leading kits
8:22
for use and forensic labs like yours.
8:25
In addition to all of that, and I'm about to show it to you,
8:28
it has a really easy-to-use software interface,
8:33
and to cap it all off, it's installed and supported by
8:37
Thermafisher scientific directly through our global
8:41
support team.
8:44
So that's what I'm excited to show you today, and I really
8:47
appreciate you sharing those topics with me and answering some
8:51
of my questions to get an idea of where you're at and what it
8:56
is that this might be able to do for you.
9:00
So I know that you already have these instruments in their
9:04
first iteration in your laboratory in order to do the
9:08
automated purification process.
9:12
And so I'm pleased about that, thrilled that you've got that.
9:15
And what I wanted to do with you today is walk you through the
9:19
new software that combines all of those portions of the workflow
9:24
that I've talked about through quantification, normalization
9:28
and amplification, in addition to the purification that you're
9:31
already familiar with because of the validation of your current
9:35
HID and MBSPresto systems in your laboratory.
9:39
So are you ready for me to let you have a look at this together
9:43
right now?
9:44
Sneak Peak, I love it.
9:47
What I've got up in front of me is the welcome screen to the
9:51
interface of this software that will be your real centerpiece
9:55
of all that will walk you through each of the different
9:58
workflows that are necessary for what we're going to look at today
10:01
and what the instrument is going to be capable of.
10:04
Your purification workflow is available through this simple
10:08
dropdown starter menu.
10:10
And from that, what you can do is drop down in this kit
10:14
selection area where you have two kits available to you that
10:19
are our kits for your use.
10:21
The PrEP file and the PrEP file are BTA extraction kit.
10:26
The BTA kit, of course, is there for more challenging samples.
10:32
The bone, the tooth enamel being the BTA acronym there.
10:36
But for those samples that you might have a protocol
10:39
validated for if you're to use that kit, today for the
10:43
benefits and the purposes of this demonstration, I'm going to
10:46
just choose the regular PrEP file or extraction kit.
10:51
And then finally, before we get into the meat of it, you must
10:54
enter a user name.
10:55
And so for today, I'm just going to put my initials in there
10:58
which are not DD, they're DJ.
11:00
So we'll enter that and click continue.
11:04
First thing to do is acknowledge that you're wanting to make
11:09
some edits to this by clicking that button that's at the
11:12
bottom and in the center so that you can tell the system that
11:17
you're going to make edits that will be tracked and logged
11:20
so that you can have an audit trail and some files generated
11:25
for troubleshooting should they need to be used in that
11:28
regard downstream.
11:31
So we will click that and then you can start choosing things
11:37
such as your input lab software, so your lice samples.
11:41
What are you going to put them into the purification
11:44
process from?
11:45
You have a choice of tubes, the Kingfisher, Deepwell plate
11:49
or a spin and filter 96 well plate.
11:52
And so for today, I'm just going to choose the tubes as an
11:56
input labware for those samples.
11:59
And then when the samples are purified, you can choose what
12:03
you want them to be alluded into, what you want those samples
12:07
to be deposited into.
12:09
So just to make this interesting, let me pick from a menu that
12:14
gives you these three options and put them into a Kingfisher
12:18
Deepwell plate.
12:20
Next, you can choose the sample volume that you're going to
12:24
begin the purification of those samples.
12:26
We'll leave it with 300 microliters for now and move
12:30
over to your illusion volume.
12:32
You get to choose how much you want to have as a volume in
12:37
your element.
12:38
So it's set here for 60 microliters.
12:41
You can go anywhere down to 20.
12:43
If you go below 35, we suggest that you have some extra
12:46
validation studies done, but anything up to larger volumes
12:50
of 290 there.
12:53
So ladies, what would be an illusion volume that you'd like
12:56
me to set this at?
12:58
25.
12:59
25.
13:00
All right, we're going low for 25.
13:04
And we just slide that down to 25 there.
13:07
And you can see that is set.
13:09
Now, the next thing to do is to tell the instrument where
13:13
your samples are and what they are in these tubes.
13:17
So you can either do one of two things.
13:19
You can choose this auto generator work list sample and
13:22
simply tell the system that you've got anything up to
13:26
96 samples to work on here.
13:29
And it will just number them one through 96 and give you a
13:32
generic work list to work with.
13:35
Or you can preload or you can load the pre-prepared
13:39
work list by choosing an Excel file that has the sample
13:44
numbers in them and details of those samples.
13:46
And for the sake of today, what I'm going to do is choose a
13:51
work list that was readied for this demonstration that has
13:56
96 samples in it by choosing that from a navigation
14:00
menu here, opening it and it will load it directly into the
14:05
system.
14:06
Now, before I move on, there's a couple of other
14:08
buttons here that you might want to consider using.
14:13
The barcode scan button, if you were to check this and turn
14:16
it on, has capabilities of checking against barcode
14:21
information that are attached to your samples or the plates
14:24
that are being used in this.
14:27
All prompt in you to do that and create those files.
14:30
We'll not turn that on today, but that's something we can
14:33
easily work with you in helping you understand and
14:36
utilize for tracking of samples.
14:39
And this checking reagent volume button as well, which just
14:43
adds another five minutes or so to the entire process and
14:48
allows the instrument to go through and do a double check
14:51
that the right volumes of reagents are in the right
14:55
places before you press start on your process for
14:59
purification.
15:00
Again, we'll leave that off for today because this
15:02
demonstration piece of software is not attached to an
15:05
actual instrument, so it would hinder us from moving
15:09
forward, but that's what that is there for.
15:12
And then finally, at the bottom here, you'll see a run
15:15
recovery menu.
15:17
And this is in case you have some kind of catastrophic event
15:21
happening, you'll have maybe the power goes off, something
15:24
happens that was unexpected, and you need to start again
15:28
from a particular point in the process.
15:31
You can easily just open up this dropdown menu, and these
15:34
will become obvious as to what these steps are as you work
15:37
through the process, but you can go back to any of these
15:41
steps that were part of the purification process and take
15:45
that sample set and start again at that point so that you're
15:49
not losing your samples should you have something, as I said,
15:53
like a power outage while you're working through the
15:56
processing.
15:57
If you need to go right back to the original Kingfisher
16:01
presto step, then this would be the button you pressed there.
16:04
So here's where it gets exciting.
16:06
We save that, and then we simply press Continue.
16:11
And Continue takes us on to the next page, which is a
16:17
schematic on the top there of the deck of the instrument, and
16:23
then some details about what you're going to put where on
16:26
that deck.
16:27
And I love this page because it makes it really easy.
16:29
It's intuitive to see where things are.
16:32
If you hover over any of these numbers that are on the deck
16:36
schematic, it'll show you a photograph and tell you what
16:40
that is and what to do sometimes such as turning on the Kingfisher
16:44
presto system.
16:45
Looking here to the tip, comb, and the illusion plate
16:49
position there on the Kingfisher presto.
16:52
If I move over here to 12A, for example, it tells you to
16:57
load a deep well plate there and label it with Wash A1.
17:02
So, and that's an important point.
17:04
Some of these plate positions have suggestions that you should
17:08
label them, and we would recommend that you do that so
17:12
that if anything wouldn't need troubleshooting down the road,
17:15
we could easily ask for those files from you, and we could
17:18
see what plates were in which positions when something might
17:22
need to be dealt with.
17:23
But that's the schematic of the deck layout of the instrument,
17:29
but the schematic itself labels each one of these
17:32
positions with numbers.
17:34
And those are really important because when you're putting
17:37
on to the deck, that which you need to do the purification of
17:41
these 96 samples that you've put in through your work list,
17:45
you can simply go to this Wash buffer A, which says that it
17:50
needs to be entered into position 7C.
17:55
And here's the trough.
17:55
If you hover over 7C, it's a 200 mil trough, and you can add
18:01
92 mils of Wash buffer A into position trough 7C.
18:08
Isopropanol here.
18:10
It's necessary if you see this, when you click on it in
18:13
position 9B, it flatches on the corresponding chart here to
18:20
the right hand side.
18:21
Position 9 is this on the deck layout where you see the
18:26
various troughs that are necessary for the reagents that
18:30
go into your purification process.
18:33
Similarly, in 9E, there's a trough that will contain Wash
18:37
buffer B, and there you need 38 mils of Wash buffer B.
18:42
And then in the F position of position 9, that trough will
18:47
contain 7 mils.
18:48
In this example of elution buffer.
18:52
Now, moving on to the tube adapter that is in position 10
18:58
here, this is where you're going to add your magnetic
19:00
particles.
19:01
And it tells you here that you're going to need 466
19:06
microliters of those magnetic particles per tube.
19:10
You can see that again by hovering over that adapter
19:13
photograph, what that position looks like on the deck and
19:17
within that tube adapter tube.
19:19
And that's where you would add those particles at that
19:22
volume per tube.
19:25
One other great feature of this screen is that if you need
19:31
some extra guidance on that, you can click on this guidance
19:34
mode button.
19:35
I'm not going to do it now because it takes you through
19:38
various videos of each one of these areas of the deck.
19:42
About 20 seconds or so long for each one, and you'll work
19:45
your way through them so that it's a step-by-step video
19:49
guide for extra clarity on how and where you put the
19:53
various components, reagents, on this deck, step-by-step,
19:58
as I say.
19:59
And then finally, you have your tip requirements in the top
20:03
right here.
20:04
Position 8 for your 1 mil filtered tips.
20:08
There's three areas.
20:09
You can put those tips there.
20:11
And you need at least 216 of those to perform the
20:15
purification of these 96 samples that you've put in here.
20:19
And 96 of the 300 microlitre filtered tips in position 11
20:26
here on the deck.
20:28
So that's how you set up the system for what you're
20:31
asking it to do with the purification of those 96
20:34
samples that you've put in through that work list.
20:37
And from here, you simply click Continue, and it will ask
20:41
you to verify the tips and the correct positions.
20:44
And then press Start, and it will begin the instrument
20:48
protocol of purifying your samples into your 25 microlitre
20:54
illusion that you've asked it to.
20:56
And so I hope that that for the purification portion of it
21:00
is clear and easy.
21:02
And wonder what your feedback or understanding of that is if
21:07
you have any questions of that, Kimberly or Cindy.
21:10
Do I have a question for you, Dave?
21:13
So if you have less tips than what it's asking or less
21:18
the agent than what is listed, will it let you know?
21:22
Or will it pause during the run to let you know?
21:25
And the post during the run, this is all to be set up ahead
21:28
of time.
21:29
And so you need to verify on the next screen that you have
21:32
the correct amount of tips.
21:33
And you'll show the instrument where you've entered those
21:36
tips.
21:37
So for example, at least the 216 that you need, you've got to
21:42
do a double verification and identify for the instrument
21:45
where those tips are sitting there.
21:48
And if you remember from the previous screen, if you wanted
21:52
to turn on the volume reagent, the check reagent volume portion
21:59
of this too, it will take that five minutes to make sure that
22:03
it's double checking for you what you have volume wise in the
22:08
various areas that are necessary.
22:10
So it does have those checks enabled for you and it helps you
22:14
to verify that as you walking through this process, Cindy.
22:18
So let's come out of this module and go back to that start
22:22
screen so that we can move on to the next portion of the workflow,
22:25
which would be the quantification workflow.
22:30
Similar to how we did the purification, set this up through
22:33
an option of the kit you would like to use.
22:35
It's really easy this time because this is set up just to be
22:39
used with our premium quantification kit, Quantifylet, Trio.
22:45
In the next line, you can do what we did at the purification
22:48
step, give this a run name of your own liking or leave it as the
22:51
default and then enter in the user name again so that we can
22:56
move on to the setup for your quantitation process here.
23:01
Now, this is where you get to make those same types of
23:05
decisions as you did on that first screen for purification,
23:08
but now for your quant setup.
23:10
And I believe that where we left off was a Kingfisher deep well
23:15
plate with your samples in after elution last time.
23:20
So let's pick that and assume that we're going to be using
23:23
the Quant Studio 5 system, but you do have the option to
23:27
switch to the 7500 real time PCR system if that's what the lab
23:32
chooses to use here.
23:35
Now, in order to tell the system what it is that you're
23:39
going to be processing in quantitation, you need to
23:44
again choose a file.
23:47
So let's choose that work list so that we have it loaded here
23:51
and you'll see that numbered in this scrollable work list from
23:55
1 through to 96 with some options at the top here for a
23:59
couple of controls that you're going to need to use for your
24:05
setup plate with a positive control and the NTC or the
24:10
no template control there.
24:12
Finally, in this setup portion, you get to choose if you want
24:17
the robot to create a new standard curve from the DNA
24:21
standard that's included with the Quant Triage Kit, you want to
24:25
use existing pre-prepared standard curves that you've saved
24:28
from a previous experiment or that you don't want to use a
24:32
standard curve at all for this experiment, perhaps you're
24:37
using that protocol in your lab with a virtual standard curve.
24:42
So we're going to ask it to create a new standard curve here
24:46
and it automatically knows then that you need to create that
24:49
for a five point standard curve.
24:51
You can easily switch this to a six point standard curve with
24:54
a click of a button here.
24:56
The same barcode scan capability is there too for you
24:59
which will ignore for the purposes of this.
25:02
And this is where I really enjoy this setup here.
25:05
You get then to choose if you would like from a series of
25:09
templates that are already preloaded and available for you.
25:13
A default five point standard curve
25:17
entered onto the plate setup for you with duplicates of each
25:22
one of your samples or you can move forward to a default
25:26
five point single sample quantitation plate setup here.
25:31
And there as you scroll through here, there's the same here
25:34
for your six point standard curves or a virtual standard
25:39
curve too.
25:39
So what I'm going to choose for the benefit of this demo is
25:43
the five points standard curve single sample plate setup
25:49
and apply that template to your output plate map here
25:54
so that it puts those samples into that plate map for you.
25:59
And then from here have another couple of options.
26:03
You can either use that as is or you can replace samples.
26:07
Let's say you don't want to process sample 85, but you'd
26:10
rather put a positive control of yours in that position.
26:14
You can drag and drop that sample and remove that target
26:17
from the plate, go back to your work list and simply drag
26:21
and drop a positive control into that position on the plate.
26:26
So you can remove any of the other samples that you wish
26:30
and replace them with samples from your work list as you wish
26:34
as you go through that sample work list there.
26:37
Now, what you'll notice is we had 96 samples,
26:40
but we're only processing 84 in this plate map here.
26:45
If you go to the very bottom of your work list,
26:47
you'll see that those samples are identified very clearly
26:51
by flashing red symbols around those samples.
26:54
Just to tell you, we know that these haven't appeared
26:57
on your plate map, not to worry.
27:00
What you can do is easily go to this export work list,
27:03
click that button and it automatically makes another work
27:06
list for you to come back and use so that you can process
27:09
the remaining samples.
27:11
So you're not going to miss utilizing all of those samples
27:14
should you wish to process them all.
27:16
Now, if you think that this is the type of plate setup
27:19
that you like or you want to make it a different way
27:22
for your ongoing use for other users in the lab,
27:25
you can actually save this, save this plate map simply
27:29
by entering a name for it and you put that as part
27:32
of the templates that are available to you
27:34
or any of your colleagues in the lab moving forward.
27:37
So you might have that as part of your SOPs.
27:41
From there, very simply you click continue
27:45
and you get to a screen that is now familiar to you
27:49
with the deck layout at the top.
27:51
And again, these areas here that tell you how much
27:55
of each of these samples or buffers need standards,
27:59
this DNA standard, for example, in position J
28:04
on the multi-tube adapter that sits in position 10
28:08
on your rack, on your deck there,
28:11
how much of that you need to add.
28:12
So 30 microliters of the DNA standard,
28:16
plus five empty tubes and positions one through five
28:20
highlighters and green here,
28:22
so that your standard curve samples can be made
28:25
in order to run this process for you.
28:29
So that's how you set up the deck ready
28:32
for your quantitation set up reaction,
28:37
to set up your plate for that.
28:39
Another area to point you to is the change in filtered tips
28:43
and they're now asking for 50 microlitre filtered tips
28:47
and you need 109 of those in these positions
28:51
of any of these positions eight here on the deck.
28:54
And as you would imagine, you need to be directed
28:58
to put your elution plate here in position four
29:02
so that those samples can be drawn from
29:04
in order to set up that quantitation plate.
29:07
So everything is intuitive as far as where it directs you
29:11
to put all of the reagents, labware,
29:14
and your samples in order to move forward with this.
29:18
Then you click continue again and the robot goes
29:21
about its business and produces for you an Excel file
29:24
as an output file to take forward to your quantitation
29:29
instrument and be able to run that quant reaction there.
29:34
And so hopefully that's easy and that's intuitive
29:37
and you can quickly work through where
29:41
and how you need to put your deck together in order
29:44
to get your quant plate set up in that manner.
29:48
And any thoughts on that ladies and any questions
29:51
about it as we get ready to move on to the final portion
29:55
of this demonstration?
29:57
- I had a quick question for people like me
30:00
who might forget one of these things to put on the deck.
30:05
Is there a check system throughout or in the beginning
30:10
when you say continue, go to the instrument?
30:13
Is there kind of a check system that says,
30:15
did you put this on area 10?
30:18
Did you put this for the tips in area eight?
30:20
Things something like that?
30:22
- When you press continue certainly for those tips
30:24
you'll be asked to verify where those are
30:27
and you will go through that process of confirming
30:30
that you have in the right position those items
30:33
and those components so that you can move forward
30:36
with this reaction, Kimberly.
30:38
Hopefully it's as intuitive to you as it is
30:41
and looks throughout the course of this demonstration.
30:44
So moving on to our last workflow
30:46
which is the amplification and normalization portions
30:49
of your setup.
30:50
We are able to go into these menus
30:53
and select from a drop down all of the kits
30:56
that we have available, global filer,
31:00
global filer IQC, verifiler, NGM direct,
31:03
Wi-filer plus and then a large reaction,
31:06
1000 reaction global filer kit two.
31:09
So I'm gonna choose the regular global filer 200 reaction kit,
31:14
give it a run name, leave it at the default
31:16
or change it should you wish to
31:18
and put my own username in there again.
31:21
Continuing on to the screen where you're able to now
31:25
make your selections in order to set up
31:27
the amplification reaction plate,
31:31
you'll be familiar again with this concept
31:33
and from there choosing what the input
31:36
from a drop down menu might be.
31:38
So a plate is the default but we put our illusions
31:43
into a Kingfisher deep well plate.
31:46
So I'm gonna choose that as there is indicated
31:50
from that menu and over here whichever CE instrument
31:54
you wish to use from our portfolio, the 3500 series,
31:58
the SEK Studio or the Flex series as well.
32:02
For today's demo, I'd like to use the SEK Studio 8 cap flex
32:07
genetic analyzer.
32:09
So it makes it really easy for you downstream.
32:12
Now in selecting the samples and the setup
32:16
of the reaction plate,
32:18
I'm gonna assume that you have the quantitation data
32:20
in a file, let's choose the original work list
32:24
from that file selection menu
32:27
and then the associated file that will allow you
32:32
to input samples with quantitation values
32:37
for this portion of the method.
32:41
Now when we go to our templates,
32:44
you will be able to choose
32:47
and the most appropriate template
32:49
or create your own with our assistance if you'd like.
32:53
We today are gonna choose not a duplicate sample one
32:57
but an eight cap single sample template
33:01
which I will apply.
33:03
And what that will do is take those samples across
33:07
to the reaction plate and the other items
33:10
that are displayed on the right hand side here
33:13
of your screen.
33:15
And let me go back to the work list
33:17
so that this stops scrolling and show you
33:20
that if you choose from here, edit again,
33:23
you can make changes to a couple of things
33:26
that are really interesting.
33:27
First of all, the global target concentration
33:31
for all of the samples.
33:32
Maybe you wanna set it at one nanogram
33:34
for all of your samples that you're processing.
33:37
You might wanna slide it up.
33:38
Maybe for some reason wanna do 1.3, 1.5,
33:41
anything between 0.1 and four nanograms
33:43
is available for you globally.
33:45
So if you set that there at one nanogram, that's great
33:49
or you can go to any sample, click on it
33:53
and you can enter for whatever reason you have
33:56
available to you a different target.
34:00
I'll put 0.8 nanograms for sample six in there,
34:04
submit it and the system will save that
34:07
and tell you what it's doing with that sample.
34:10
You can do that bespoke for each sample
34:12
or just leave it at the global concentration target there
34:16
as we've set.
34:18
Now from here, you'll see that those samples
34:20
are already pre-populated because of that template.
34:23
If you wanted to drag and drop out a sample
34:27
such as 82 and move it out of that plate
34:31
and save it for later, you can.
34:32
Perhaps you want to replace that with, for whatever reason,
34:36
sample 95.
34:37
If you can go to your work list, click on that,
34:40
drag it into that open position and drop it
34:44
and it will replace that sample into that position.
34:47
Now you'll see all of these red highlighted samples
34:51
are doing what we've looked at before,
34:53
telling you that they haven't been able to be
34:57
put onto this plate just because of real estate
35:00
and you can click again on this export work list button
35:05
to create a work list that will incorporate
35:08
those leftover samples onto a downstream work list.
35:11
If you would like to look at the details
35:14
of each one of these plates that are going to be utilized
35:16
on the instrument for making this reaction plate
35:19
the way that it needs to be, you have your input samples
35:23
that is your Kingfisher deep well plate
35:26
that has your original samples in it.
35:29
Then the dilution plate, this is what it's going to do
35:32
and what it's going to need for each one of those samples
35:35
in the dilution plate there.
35:37
And the details, if you just hover over any one of those cells
35:40
or sample numbers, you'll see what the details
35:44
of that dilution are based upon the quant value
35:46
that's been incorporated and imported into this
35:50
part of your workflow.
35:53
- I have a question about the dilution plate.
35:56
Can they be reused?
35:58
For instance, if we did the amp and say
36:03
that the electropharyngeal data looks a little bit funny
36:08
and we want to reamp, can we work off of the dilution plate
36:15
to reamp it or it's a whole new setup again?
36:21
- That's a great question.
36:22
You'll have that dilution plate available to you
36:25
and there's, I'm just hovering over one sample,
36:27
you'll see that you have more than enough volume there
36:30
to be able to use or even cherry pick out
36:34
and put in a new work list, those samples,
36:36
if you have a concern with one or two of those samples
36:39
and put it into a downstream work list
36:42
for using again, Kimberly.
36:43
So I hope that's a help to you
36:48
in order to be able to use that information
36:50
and take out any of those samples
36:53
and put them into a new place
36:54
should you need to use them
36:56
for a brand new amplification setup.
36:58
So from here, what we would do is click the continue button
37:01
and take you to that all familiar screen
37:04
and then going to that deck layout page
37:08
where again now it becomes the same process
37:11
that you've been used to on the previous steps
37:14
of seeing where everything needs to be on the deck
37:18
and from there, very simply click continue,
37:22
verify those same components again
37:24
and your system starts to run
37:27
and prepare those dilutions for normalization
37:30
and also the output reaction plate
37:33
that you can take off the instrument
37:35
and put directly onto your thermal cycler
37:38
and then take forward to process on your 3500 CE instrument
37:43
and that hopefully is as intuitive as it gets
37:51
in setting up those three real important portions
37:54
of your workflow within your lab
37:57
to save you the time and the processing necessities
38:02
that you need to do in order to get you
38:04
to this place efficiently and effectively.
38:07
Any thoughts or questions about that ladies?
38:11
- I particularly like the drag and drop part
38:16
of editing the plate
38:19
because I think along with many labs here
38:24
in the area that we have a soft a quant
38:28
allowance in our procedures.
38:30
So if there is a sample that is too low
38:34
or not worth going forward for DNA
38:37
that we won't continue it for applications.
38:42
So when we're doing the application setup,
38:44
as I saw that you can just remove that from the plate
38:47
and just simply put it in the trash bin.
38:50
So that's really easy.
38:52
Yeah, that looks like that.
38:55
I like that.
38:57
- And that's a good point Kimberly
38:58
and there's a little feature which is not contained
39:00
within the sample set that we've used today.
39:02
But if you try to amplify a sample
39:06
that you're not gonna be able to reach the target of
39:09
that you've set in that amplification plate,
39:12
the work list will actually and the plate map
39:15
will actually highlight it in orange
39:18
so that you know fine well that it's not going to do
39:21
what you're trying to do with that sample.
39:23
So you have that double bagging effect if you like
39:27
to make sure that you're safe
39:28
and that you understand what you're doing
39:30
with each one of your samples.
39:31
It'll do it on the plate map
39:32
and it will do it on your work list for you.
39:34
So again, that's a great feature of this software
39:38
to make it even easier for you to identify
39:41
those types of samples.
39:42
Do you think this will make things easier for you
39:44
in your lab throughout all of these workflows
39:47
and help you set up and claim back some of that time
39:51
that you could use better somewhere else?
39:53
- Absolutely.
39:54
I think we are going to love this.
39:56
And even from the validation and the implementation side,
40:00
I think it's gonna be a lot easier.
40:03
I'm already formulating what kind of worksheets we need
40:05
to create for analysts and to verify the steps
40:09
and this has reduced so many checks.
40:13
So it'll make that easier as well to develop a protocol.
40:17
- That's great to hear, Cindy.
40:18
Thank you for that feedback.
40:19
Really appreciate it.
40:21
I guess I really just need to ask,
40:23
what are you gonna do with all of this time
40:24
that you're gonna save?
40:26
(laughing)
40:28
- It allows us to focus on maybe some other things
40:33
in other areas of the laboratory or and TRs.
40:36
I mean, technical reviews.
40:37
That's always a big bottleneck for us
40:40
as that we cannot get to them
40:43
because we're processing.
40:45
- Excellent. That's great to hear.
40:46
Well, thank you so much for joining me today.
40:49
I hope it's been useful.
40:50
It sounds like it has and I'm glad that you're excited
40:54
to get this in your hands.
40:55
I know that you're gonna be doing that very shortly
40:58
but I wanna just tell you that I appreciate you joining me
41:02
for this reveal of this software
41:05
that's gonna enable your instrument to do so much more
41:10
that you've been asking for actually
41:13
and hopefully will make things so much more efficient
41:17
and effective for your important workflows
41:20
within your laboratory.
41:21
- Thank you.
41:22
Thank you, Dave. We're so excited.
41:24
We can't wait to get it online.
41:26
- Oh, likewise.
41:27
Well, we're looking forward to continuing
41:29
and partnering with you.
41:30
So thank you so much again for your time today
41:32
and good luck as you move forward
41:34
and utilize this in your successful work
41:38
within the San Mateo County Sheriff's Office,
41:40
Forensic Crime Lab.
41:42
We appreciate your partnership.
