Concepts in Biochemical Pharmacology pp 108-117 | Cite as. Bioassay is a biochemical test to estimate the relative potency of a sample compound to a standard compound. A method using white rats has been devised for the bioassay of diuretics. Two types of bioassay used for measurement of serum LH bioactivity include the mouse interstitial cell testosterone assay ... Pharmacology, Biodiversity and. That compound will be the drug candidate that will go on to pre-clinical trials. Bioassays are typically conducted to measure the effects of a substance on a living organism and are essential in the development of new drugsand in monitoring environmental pollutants. sm29may1996@gmail.com. animals, tissues, plants) and a response (ex. Bioassay. 10 2. Each question carries 10 marks 1. A Bioassay, also called biological standardisation, is a type of scientific experiment. Points to be discussed 1- Definition of bioassay 2- Discussion of applications of bioassays in pharmacology 3- Comparison between Bioassay and Chemical assay 4- Screening of drugs: types and steps of biological screening 5- Factors that affect the response to the drugs Lab work Training on handling and injection of animals. A bioassay is a procedure for determining the concentration, purity, and/or biological activity of a substance (e.g., vitamin, hormone, plant growth factor, antibiotic, enzyme) by measuring its effect on an organism, tissue, cell, enzyme or receptor preparation compared to a standard preparation. 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. 1.
