Data analysis
Data analysis add-ons offer a wide range of capabilities, ranging from analytical methods over comprehensive analysis to assay workflows and statistical process control.
Biological Assay Package
Use the Biological Assay Package for potency analysis of biological assays. The add-on comes equipped with a highly flexible test system to qualify your assay. You can perform combination calculations to obtain the reportable value from independent assay runs and use historic assay data to develop equivalence margins.
Use case: Automate a bioassay workflow
For some biological assays, determining relative potency within a single run is not sufficient. In these cases, you perform multiple individual assay runs and then combine the resulting data to obtain a more reliable final potency estimate. The challenge is to combine these individual results efficiently and reproducibly, particularly in regulated environments or when preparing for automated workflows.
Set up the assay template
Performing daily assay runs is a common scenario in Good Manufacturing Practice (GMP) environments. PLA 3.0 supports routine assay analysis by providing assay templates. You use these templates to prepare a standard setup for the assays that PLA 3.0 generates.

      - Create the assay template
        Assay templates hold settings such as assay elements, dilution sequence, analysis, and suitability tests.
      - Set up the assay elements
        Assay elements are the building blocks of your assay. They are the starting point for the setup of your analysis workflow, as they represent the individual samples you want to evaluate in your analysis.
      - Set up and assign the preparation schemes
        Preparation schemes correspond to industry-standard practices of dose preparation protocols. They let you efficiently assign dilution sequences and replicate settings to assay elements, ensuring consistency and reducing redundant input during setup.
      - Define the plate size
        Define the plate size for your assay template to establish how many rows and columns the plate uses.
      - Define the analytical settings
        Use regression models to set up regression analysis for your assay elements. Selecting the appropriate regression model is an important step in defining your assay.
      - Create the suitability tests
        Suitability tests are essential for verifying the integrity of both the overall assay and individual samples. They let you prove the validity of your calculation.
      - Define the assay layout
        Define how the samples are arranged on the plate for this use case.
    - Set up the combination template
      Combining assay results is a common task in regulated environments, especially when you need to report results from repeated assay runs. PLA 3.0 supports combination calculations by providing combination templates. You use these templates to prepare the logic according to which PLA 3.0 combines results.
    - Set up the protocol template
      Protocol templates act as reusable workflow definitions. They let you organize recurring analysis tasks, such as evaluating multiple assay runs, applying predefined combination logic, and generating consistent protocol documents. By setting up the protocol template, you create the structure that PLA 3.0 follows when it processes assay data.
    - Perform routine analysis
      Use the protocol template to run the routine analysis for your bioassay workflow. Routine analysis applies the workflow logic you defined earlier and processes the assay data as it becomes available. This step shifts from preparing templates to executing the actual analysis and evaluating the assay results.

Set up the assay template

Performing daily assay runs is a common scenario in Good Manufacturing Practice (GMP) environments. PLA 3.0 supports routine assay analysis by providing assay templates. You use these templates to prepare a standard setup for the assays that PLA 3.0 generates.

This is the first step in setting up an automated bioassay workflow.

Before you begin

This task uses the Quantitative response assay document type of PLA 3.0. We recommend becoming familiar with this document type before setting up the assay template. For details, see the Quantitative response assays topic.

About this task

Assay templates define the settings that PLA 3.0 uses to generate Quantitative response assay documents during the automated workflow. These settings include assay elements, dilution sequence, and analysis steps. Assay templates also store suitability test settings that check whether the assay provides valid results.

Procedure

To setup the assay template:

Begin by creating the assay template. Then define the assay elements and preparation schemes. Define the plate size and configure the analytical settings and suitability tests. Complete the setup by defining how the samples and dilutions are arranged on the plate.
