As a reminder, Signals Screening enables biologists to perform all the foundational steps of screening:

1. Load data from instruments. Signals Screening brings the power of the SciStream instrument file parser to the screening scientist and ties it more directly into the data processing workflow.
2. Develop and reuse plate maps. A key part of the screening process is the definition of the layout of the test articles on a plate. The Grid Plate Editor overhauled this part of the screener’s process and creates a significantly improved process for individual plate design and library management.
3. Normalize the data with standard or customer-defined methods. We provide out-of-the-box the most standard normalization methods and customers can easily define their own normalization equations in an intuitive interface.
4. Define and review Curve Fits. Any measurement from the plate and be selected for input into a parameterized and customizable curve fit engine, and the resulting curves can be reviewed and adjusted by knocking out aberrant points.
5. Publish the results to Signals Lead Discovery. As a final step, a processed dataset can be published to Signals Lead Discovery to use by the lead discovery scientist in deciding which candidates to advance.
6. Workflow authoring and reuse. The whole user-defined workflow can then be saved to Signals Screening so routine assays can be run, and data processed in an efficient and repeatable fashion.

These new capabilities are additions on to the prior Signals Screening capabilities, such that our customers are now enabled for Basic Screening, High-Content Screening, as well as SPR.

Summarizing, the Signals Screening product includes:

1. Core Screening Apps to support normalizing and processing results
2. Calculation Explorer to enable rapid assay development and flexible new data processing

   • … and much more!

This release of PerkinElmer Signals™ Screening brings a new enhancement to the Editable Data Grid and allows historical data integration as well as new data publication app. This update also contains a few usability enhancements and fixes several small bugs.

1. Adding plate specific details through the Editable Data Grid: Screening scientist often must join the list of Compound IDs (and any other plate specific details), while assembling a dataset. This allows for each plate maps to have specific meaning for that day's screening run. In 2.4.1, this ability is enhanced by leveraging the flexibility of the Editable Grid (so the user can copy-paste in the compound IDs) and allow for a more flexible join to be defined, using a mapping interface / workflow like that in the Calculations Explorer.

   Users can now:

   • Add Compound IDs and other columns can be directly added to the Editable Grid display.
   • Add their data in the Editable grid and define how that data should be joined to the Imported data and Plate Map.
   • The app saves the table definition and join conditions into Protocol.
   
   Editable Data Grid Enhancement: Add plate specific details

2. Normalization App Enhancements: along with fixes for previously noted bugs the enhancements to the normalization app now utilize the Calculations Explorer as its core engine, such that the calculations are consistently using a single calculation methodology.

   • In addition to an expanded set of core Normalization Calculations, the App can access and apply any stored Calculations Explorer template document that has been configured to act as a Normalization calculation.
   • In all cases, the Scientist is guided through the Normalization process with point-and-click ease to select the Well Type and Positive / negative controls using the same interface as in the prior version of the Normalization App.
     Expanded normalization app in Signals Screening
   • Curve Fitting flexibility. Signals Screening 2.4.1 includes an overhaul of the core curve fitting engine and algorithm to expand its capabilities, increase its accuracy, and provide more facilities for curve QA/QC control. User control over which core curve fitting algorithm to use either the Levenberg-Marquadt algorithm and the robust algorithm IRLS.
   • Support for weighted curve fits including all the standard weighting methodologies.
   • Support for constrained curve fits, that will properly limit the range of allowed returned parameter values to user-defined ranges.
   • Significant usability improvements to curve fit QA/QC workflows.

3. Ability to pull in historical (batch equivalent) data for data trend review before data publication

   Scientists can now pull all historical results for equivalent compounds or compound batches into their current Signals Screening workflow. This feature enables scientists to confirm consistency with historical trends before publishing new data.

4. Publish to SLD as an App:

   Signals Screening 2.4.1 includes and utilizes the new SLD Publication App, such that a fully configured publication configuration can be saved as part of a Protocol.

   The final step of a screening workflow is to publish results into Signals Lead Discovery, currently this must be done manually at the end of each protocol. User will be guided to capture following data through this App and process:

   • The Measurements that represent the assay endpoints (e.g. IC50).
   • The associated Measurements that represent the penultimate details that were used to derive that assay endpoint (e.g. the individual % inhibition data points that defined the dose-response curve).
   • The curve thumbnail image, if a curve fit is defined

Product Compatibility

These applications require TIBCO Spotfire® Professional 7.11 LTS and 10.3 LTS Signals Screening is available for onsite deployment.
