As a leader in specialized and complex bioassay development and testing, BioAgilytix combines state-of-the-art cell-based assay facilities with a veteran team of scientists well-versed in the quality and regulatory demands of biological assay development to support customers innovating in the areas of biologics, biosimilars, and biobetters.

Our track record has proven our ability to effectively develop, qualify, and validate a diverse range of bioassays to meet stringent scientific and regulatory demands across numerous industries and disease states.

Use the paragraphs below to learn what a bioassay is, how it can be used to effectively determine concentration and potency of a biological substance, the types of platforms that best support bioassay needs, and how BioAgilytix brings a differentiated level of expertise to the bioassay services we provide.

What is a Bioassay?

Premier Bioassay FacilityBy defintion, a bioassay is the “determination of the relative strength of a substance (as a drug) by comparing its effect on a test organism with that of a standard preparation.” They are used to measure the biological activity and effects of a substance, like a hormone or drug, on a living organism such as a live plant (in vivo) or tissue or cell (in vitro).

Bioassay services are most often employed to determine the concentration or purity of substances including vitamin, hormone, or plant growth factor by measuring their effect on tissue, cells, enzymes, or receptors. The general approach involves measuring the biological response of the live material at several doses, to understand the dose-response relation.

As such, the advantage of the bioassay testing procedure is that it can help determine both the concentration and potency of a sample, which is necessary for regulatory submission and lot release testing of biopharmaceutical products.

How are Bioassays Used?

The primary purposes of bioassays are to measure the pharmacological activity of new or chemically undefined substances, as well as to determine side-effect profiles, including toxicity.

Bioassays are key in determining the potency and stability of a drug substance or product in order to establish its safety and efficacy profile. Today, they are an important component in effectively controlling the quality of biopharmaceuticals for lot release testing and manufacture.

BioAgilytix’s premier GMP laboratory is built to support the full range of bioanalytical requirements, from custom bioassay development to lot release testing and stability testing under GLP and GMP standards.

Bioassay Platforms and Applications

There are a number of innovative technologies and platforms can be used to help to automate bioassay testing processes and yield greater throughput, speed, reliability, and reproducibility.

BioAgilytix leverages a unique breadth of platforms to support the delivery of its bioassay services, including ELISA, MSD-ECL, ProteinSimple and Flow Cytometry. For a full listing of the technology platforms leveraged by BioAgilytix, click here.

By selecting the platform to optimally support each bioassay’s specific parameters, we are able to perform robust, timely analysis related to:

  • Cell proliferation: Bioassays can be used for accurate assessment of cell number increases as a result of cell growth and division. Cell proliferation is a high-sensitivity indicator of cell stress in intact cell structures.
  • Apoptosis and cell death: These assay can also be used to characterize programmed cell death, and understand the mechanisms of cell death and survival.
  • Signaling and secretion: Bioassays play a role in understanding cellular activities and coordination, and can be used to assess the ability of cells to perceive and respond to their microenvironment.
