- 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.
  - Installation
    Find details on the system requirements for the Biological Assay Package add-on and the steps to install the add-on in your environment.
  - Basic bioassay protocol
    Use Basic bioassay protocol documents to set up a workflow for producing reportable values from multiple independent assay runs. Organize complex methods, retest scenarios, and report several products in a single assay.
  - Combination of assay results
    Use Combination of assay results documents to perform combination calculations for independent assay runs, thus obtaining reportable values for the potency.
  - Equivalence margin development
    Use Equivalence margin development documents to develop and verify test systems based on historic assays and apply these test systems in new development of quantitative response assays.
  - Quantitative response assays
    Use Quantitative response assay documents to calculate the potencies of test samples relative to an established standard. You can also use them to determine absolute potencies based on stock solutions or raw materials.
  - Test system definition
    Use Test system definition documents of the Biological Assay Package to define a collection of suitability tests and corresponding margins for Quantitative response assay documents.
  - 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.

Predilution factors: Manual input

Select this option if you want to provide predilution factors directly. To add a predilution factor, double-click the Predilution factor element in the Creatable elements pane.

When the assays are analyzed, a final predilution factor is calculated by multiplying all predilution factors entered here.

Note: Predilution factors are considered after relative potency is calculated. They do not enter the calculation for model fit.
