Example of a typical process at Scripps

COMPOUND SUBMISSION
• Has the correct sample been put into the labware?
• Is the volume and concentration of the sample accurately recorded?
COMPOUND PROCESSING
• Has the sample store delivered the correct samples?
• Has the liquid handling automation pipetted the samples properly?
• Has the plate been registered correctly?
• Is the sample itself of high quality?
COMPOUND DELIVERY
• Do we have a record of what we are delivering?

Room for improvement! How can we QC samples more efficiently?

Why Do We Need Plate Auditor?
Are empty/partially filled
wells in Quadrant 1?

My db says
this well is
empty. Does
it actually
have sample
in it?

The Scripps Research Institute © 2014 – All rights reserved

Do these wells
contain precipitate?
Issues With Compound Libraries
Should these wells really be empty? What
does my database say?

Do these wells
contain precipitate?

My experiment is sensitive to purple
compounds-where are they?
The Scripps Research Institute © 2014 – All rights reserved

Are these wells
partially filled?
What is Plate Auditor?
• A custom HTS plate reader, incorporating
recent advances in machine vision, image
analysis, & the spectroscopy sciences
• It saves labor by automatically identifying
& annotating issues specific to compound
libraries:
• Colored compounds
• Precipitate / Crystallization
• Low volume / Full wells

• It can be used in “stand-alone” mode, or
integrated with automation
• Works with microtiter plates
• Fast: reads a 384 well plate in <1 minute
• All measurements are non-contact
• User-friendly, intuitive analysis software

How does it work?

The Scripps Research Institute © 2014 – All rights reserved
Before Processing

Features: Color Recognition & Classification
• Plate Auditor detects and classifies colored
compounds
• Plate Auditor identifies the “standard” colors
listed below:
Color

(uM)

Allura Red

35.1

Brilliant Green

The Scripps Research Institute © 2014 – All rights reserved
Features: Precipitate Detection
Compound plates contain precipitates which are masked by colors in the
wells:

Plate Auditor Precipitate analysis is:
• Insensitive to color
• Able to detect ppt. beyond “naked eye” inspection

The Scripps Research Institute © 2014 – All rights reserved
Features: LIMS/Corporate Database Auditing
RESULTS OF COMPOUND PLATE QUERY
IN CORPORATE DATABASE:
• Scripps database (MDL Symyx/Plate Manager)
displays several wells as empty (white rectangles
in figure on left)

RESULTS OF THE SAME COMPOUND
PLATE QUERY IN Plate Auditor
DATABASE:
• Plate Auditor compares instrument results to
records archived in corporate db
• Plate Auditor identifies discrepancies with
corporate db records(red “x’s” in figure on left):
• Colored compounds (upper left)
• Full wells that corporate db assigns as “empty”

Plate Auditor CAN BE USED TO AUDIT/UPDATE CORPORATE DB RECORDS
The Scripps Research Institute © 2014 – All rights reserved
Opportunities For Error

What new information do we obtain with Plate Auditor in the process?
• We know which wells have been filled and which have low volume
• We know which wells contain colored samples
• We know which wells contain compounds that have precipitated
What can we do with this information?
• Compare filled & low volume wells against LIMS to verify proper liquid handling & plate
registration
• Compare „color fingerprint‟ of samples against database of known samples to identify issues with
incorrect concentration & samples
• Take measures to put precipitated samples back into solution (sonication, heating, etc.)
• Keep a historical record of the health of the plate at the point when it was delivered (a receipt of
transaction)

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: 384 Well Plate Timing
To visually inspect three 384 well
plates:
Plate #1 – 3 minutes 12 seconds
Plate #2 – 1 minute 46 seconds
Plate #3 – 1 minute 40 seconds

In the same amount of time, Plate
Auditor can automatically inspect
fifteen 384 well plates!

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: HTS Library Analysis
To date, Scripps has run over 1,700 plates through the Plate
Auditor, resulting in over 2,600,000 wells which have been
analyzed for color, precipitate and low volume artifacts.

How can we leverage all of this new data to improve our workflow?

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: Low volume detection
Did my pipettor transfer all compounds properly?

Plate Auditor enables just-in-time QA of compound management liquid handling

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: Color Analysis
Plate Auditor data can be used to monitor consistency of sample color over time…

A sample provided by an external source in 2009 vs. the
same sample provided by the same source in 2011.
With Plate Auditor, we can
automatically query and
identify inconsistencies
across entire compound
collections.
Is this the same sample? Is the concentration recorded
correctly?

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: Color Analysis
Why should we care about sample color?

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: Color Analysis
Running color comparison reveals
color inconsistencies…
Sample 1

Sample 2

Two copies of plate prepared by external vendor reveal
inconsistencies
Sample 3

Sample 4

Sample 5

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: LIMS Comparison
When checking reformatted plates, CM team noticed high # of LIMS disagreement wells…

… examining the plate detail view reveals a pattern in quadrant 1…

… checking the LIMS record reveals samples in quadrant 1 are not registered …

The Scripps Research Institute © 2014 – All rights reserved
Practical Examples: LIMS Comparison

… CM team updates LIMS record and runs plate through Plate
Auditor to confirm the corrected LIMS record matches the
physical locations of samples within the plate.

Don’t take no for an answer

•
•

Two grant applications were denied during the period of instrument
development
One year was spent unsuccessfully demonstrating the technology to various
companies looking for a commercial partner

If at first you don‟t succeed… put it in the back of your truck and
drive it to a trade show (but be ready to hustle)

The Scripps Research Institute © 2014 – All rights reserved
Keep an eye open for disruptive technologies
3d printing example:
Drosophila flies used in Neuroscience research at
Scripps & FAU

•
•

Fixed design, if it doesn’t
work as desired there is
little room for improvement
~$600 for device

•

•

Custom design, enables fast
iteration, new prototypes
fabricated in hours
~ $1 for plastic, plexiglass
cover, ~$50 for USB
webcam

Keep your eyes open for new applications
The Plate Auditor was also helpful in
documenting QC failures at the factory
where our injected molded labware is
manufactured

Growth of robotics
According to a February 2014 report from Littler Mendelson (largest
U.S. based labor & employment law firm devoted to representing
management in employment): “Robotics is the fastest growing industry
in the world, poised to become the largest in the next decade. The
increasing use of artificial intelligence (AI) and related technologies in
the workplace are dramatically changing the employment landscape.”

  • 12. Why Do We Need Plate Auditor? Are empty/partially filled wells in Quadrant 1? My db says this well is empty. Does it actually have sample in it? The Scripps Research Institute © 2014 – All rights reserved Do these wells contain precipitate?
  • 13. Issues With Compound Libraries Should these wells really be empty? What does my database say? Do these wells contain precipitate? My experiment is sensitive to purple compounds-where are they? The Scripps Research Institute © 2014 – All rights reserved Are these wells partially filled?
  • 14. What is Plate Auditor? • A custom HTS plate reader, incorporating recent advances in machine vision, image analysis, & the spectroscopy sciences • It saves labor by automatically identifying & annotating issues specific to compound libraries: • Colored compounds • Precipitate / Crystallization • Low volume / Full wells • It can be used in “stand-alone” mode, or integrated with automation • Works with microtiter plates • Fast: reads a 384 well plate in <1 minute • All measurements are non-contact • User-friendly, intuitive analysis software The Scripps Research Institute © 2014 – All rights reserved
  • 15. Features: Instrument Functionality The Scripps Research Institute © 2014 – All rights reserved
  • 16. Taking an idea to market The Scripps Research Institute © 2014 – All rights reserved
  • 17. Evolution of hardware Proof of concept 1st generation 2nd generation 3rd generation The Scripps Research Institute © 2014 – All rights reserved 4th generation
  • 18. Evolution of software 1st generation 2nd generation The Scripps Research Institute © 2014 – All rights reserved 3rd generation
  • 19. Implementation How does it work? The Scripps Research Institute © 2014 – All rights reserved
  • 20. Before Processing Features: Color Recognition & Classification • Plate Auditor detects and classifies colored compounds • Plate Auditor identifies the “standard” colors listed below: Color Detected Dye Used Limit of Detection (uM) Allura Red 35.1 Brilliant Green 9.0 Blue Euroglaucine 0.6 Yellow After Processing Red Green Tartrazine 12.7 Violet Gentian violet 1.3 The Scripps Research Institute © 2014 – All rights reserved
  • 21. Features: Precipitate Detection Compound plates contain precipitates which are masked by colors in the wells: Plate Auditor Precipitate analysis is: • Insensitive to color • Able to detect ppt. beyond “naked eye” inspection The Scripps Research Institute © 2014 – All rights reserved
  • 22. Features: LIMS/Corporate Database Auditing RESULTS OF COMPOUND PLATE QUERY IN CORPORATE DATABASE: • Scripps database (MDL Symyx/Plate Manager) displays several wells as empty (white rectangles in figure on left) RESULTS OF THE SAME COMPOUND PLATE QUERY IN Plate Auditor DATABASE: • Plate Auditor compares instrument results to records archived in corporate db • Plate Auditor identifies discrepancies with corporate db records(red “x’s” in figure on left): • Colored compounds (upper left) • Full wells that corporate db assigns as “empty” Plate Auditor CAN BE USED TO AUDIT/UPDATE CORPORATE DB RECORDS The Scripps Research Institute © 2014 – All rights reserved
  • 23. Opportunities For Error What new information do we obtain with Plate Auditor in the process? • We know which wells have been filled and which have low volume • We know which wells contain colored samples • We know which wells contain compounds that have precipitated What can we do with this information? • Compare filled & low volume wells against LIMS to verify proper liquid handling & plate registration • Compare „color fingerprint‟ of samples against database of known samples to identify issues with incorrect concentration & samples • Take measures to put precipitated samples back into solution (sonication, heating, etc.) • Keep a historical record of the health of the plate at the point when it was delivered (a receipt of transaction) The Scripps Research Institute © 2014 – All rights reserved
  • 24. Practical Examples: 384 Well Plate Timing To visually inspect three 384 well plates: Plate #1 – 3 minutes 12 seconds Plate #2 – 1 minute 46 seconds Plate #3 – 1 minute 40 seconds In the same amount of time, Plate Auditor can automatically inspect fifteen 384 well plates! The Scripps Research Institute © 2014 – All rights reserved
  • 25. Practical Examples: HTS Library Analysis To date, Scripps has run over 1,700 plates through the Plate Auditor, resulting in over 2,600,000 wells which have been analyzed for color, precipitate and low volume artifacts. How can we leverage all of this new data to improve our workflow? The Scripps Research Institute © 2014 – All rights reserved
  • 26. Practical Examples: Low volume detection Did my pipettor transfer all compounds properly? Plate Auditor enables just-in-time QA of compound management liquid handling The Scripps Research Institute © 2014 – All rights reserved
  • 27. Practical Examples: Color Analysis Plate Auditor data can be used to monitor consistency of sample color over time… A sample provided by an external source in 2009 vs. the same sample provided by the same source in 2011. With Plate Auditor, we can automatically query and identify inconsistencies across entire compound collections. Is this the same sample? Is the concentration recorded correctly? The Scripps Research Institute © 2014 – All rights reserved
  • 28. Practical Examples: Color Analysis Why should we care about sample color? The Scripps Research Institute © 2014 – All rights reserved
  • 29. Practical Examples: Color Analysis Running color comparison reveals color inconsistencies… Sample 1 Sample 2 Two copies of plate prepared by external vendor reveal inconsistencies Sample 3 Sample 4 Sample 5 The Scripps Research Institute © 2014 – All rights reserved
  • 30. Practical Examples: LIMS Comparison When checking reformatted plates, CM team noticed high # of LIMS disagreement wells… … examining the plate detail view reveals a pattern in quadrant 1… … checking the LIMS record reveals samples in quadrant 1 are not registered … The Scripps Research Institute © 2014 – All rights reserved
  • 31. Practical Examples: LIMS Comparison … CM team updates LIMS record and runs plate through Plate Auditor to confirm the corrected LIMS record matches the physical locations of samples within the plate. The Scripps Research Institute © 2014 – All rights reserved

  • 33. Don’t take no for an answer • • Two grant applications were denied during the period of instrument development One year was spent unsuccessfully demonstrating the technology to various companies looking for a commercial partner If at first you don‟t succeed… put it in the back of your truck and drive it to a trade show (but be ready to hustle) The Scripps Research Institute © 2014 – All rights reserved
  • 34. Keep an eye open for disruptive technologies 3d printing example: Drosophila flies used in Neuroscience research at Scripps & FAU • • Fixed design, if it doesn’t work as desired there is little room for improvement ~$600 for device • • Custom design, enables fast iteration, new prototypes fabricated in hours ~ $1 for plastic, plexiglass cover, ~$50 for USB webcam The Scripps Research Institute © 2014 – All rights reserved
