- 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 a reportable value from independent assay runs and use historic assay data to develop equivalence margins.
- bioMérieux Endotoxin Detection Assay Package
  Use the bioMérieux Endotoxin Detection Assay Package add-on to perform endotoxin testing based on recombinant factor C (rFC), a synthetic alternative to naturally sourced reagents derived from horseshoe crabs, as offered by the bioMérieux company.
- Control Chart Package
  The Control Chart Package allows sophisticated statistical process control (for example, by plotting Shewhart I-Charts as recommended in the USP <1010>). It provides visualization options for intervals, subcharts and sidecharts, and allows you to define colors by a secondary characteristic. You can also define rules based on events and time frames.
- Dichotomous Assay Package
  Use the Dichotomous Assay Package to analyze biological assays based on quantal (binary) responses by fitting probit or logit models to estimate the potency of your samples.
- Dose-Response Analysis Package
  The Dose-Response Analysis Package provides various biostatistical methods for immunoassays, ELISA, and more. It supports you in investigating equivalence for calibration curves, provides enhanced data processing, and options for subgroup analysis.

      - Assay elements
        Assay elements are the building blocks of an assay.
      - Preparation schemes
        Set up Preparation schemes to define the doses and dimensions of your assay elements. You can set up a preparation scheme once and assign them to as many assay elements as you require. You do not have to enter redundant information.
      - Subgroup analysis
        Group your samples, for example, in spike-and-recovery analysis or assay optimization, or to create statistics for interpolated results and dose-response curve characterization.
    - Analytical settings
      To support you in defining your analytical settings, Dose-response analysis documents provide a set of concepts you should be familiar with when working with this document type.
    - Suitability testing
      Define a collection of suitability tests.
  - Equivalence margin development
    Use Equivalence margin development documents to utilize data of earlier assays to develop and verify test systems and export these systems to apply them in new assay development.
  - Test system definition
    Use the Test system definition document type to define a collection of suitability tests and corresponding margins for Dose-response analysis documents.
  - Use case: Determine total human thyroxine (T4)
    Thyroxine (T4) is a commonly measured thyroid hormone for diagnosis of the thyroid function. Determining the total quantity of human thyroxine in serum is a standard use case for interpolation on a calibration curve.

Assay elements

Assay elements are the building blocks of an assay.

Three types of assay elements are available for Dose-response analysis documents: Standard, Test, and Control:

Every assay element must reference exactly one preparation scheme. Standard samples always reference a multi-dose scheme. Test samples and Control samples can reference single-dose schemes and multi-dose schemes. By default, they reference a single-dose scheme.

Control samples with single-dose preparation schemes may also serve as positive, negative, or blank controls.
