A bioassay provides only an estimate of the potency of the unknown; the precision of the estimate should always be determined, using the data of the assay. Santrel Media Recommended for you The copyright of the text is held by Trustees of Boston University. 10 2. Bioassay is defined as the estimation of the potency of an active principle in a unit quantity of preparation or detection and measurement of the concentration of the substance in a preparation using biological methods (i.e. Department of Physiology and Pharmacology, Faculty of Medicine, University of Sherbrooke, Sherbrooke, Québec, Canada J1H 5N4.

B ioassay is defined as the estimation of the potency of an active principle in a unit quantity of preparation or detection and easurement of the concentration of the substance in a preparation using biological methods (i.e. It is a pure, dry and crystalline insulin in state. A bio-assay for effectors of osteoclast differentiation in serum from patients with bone disease. Research Results in Pharmacology 4(1): 33–42. Three types of projects are highlighted, including: developing a new chemical entity, repurposing of marketed drugs, and applying novel platform technology to improve delivery of currently marketed drugs. The ability to compare two different types of chemotaxis using a simple, rapid and accurate bioassay system should enhance future studies of chemotaxis in wild-type and mutant strains of D. discoideum.
