Phenotypic assay definition
Web6. apr 2024 · Definition. Phenotypic screening is a strategy for the identification of molecules with particular biological effects in cell-based assays or animal models. Phenotypic screening is a type of screening used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell or an organism in a desired manner. Phenotypic screening must be followed up with identification (sometimes … Zobraziť viac Phenotypic screening historically has been the basis for the discovery of new drugs. Compounds are screened in cellular or animal disease models to identify compounds that cause a desirable change in phenotype. … Zobraziť viac Animal based approaches to phenotypic screening are not as amenable to screening libraries containing thousands of small molecules. Therefore, these approaches have … Zobraziť viac • Moffat JG, Rudolph J, Bailey D (August 2014). "Phenotypic screening in cancer drug discovery - past, present and future".
