WebDec 4, 2024 · Every biological product such as vaccines, hormones, antibodies, cell therapies, complex therapeutic proteins, and gene therapies all need a bioassay or multiple bioassays to measure biological activity. A bioassay is an interesting combination of science and statistical methods to determine potency or relative potency. WebBiological assay is based on a measurable growth response from a test organism, as a result of the biological action of any compound. In many instances, this growth response will be an inhibition of elongation or a curvature of an organ such as a stem.
