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 referred to as target deconvolution) and validation, often through the use of chemoproteomics, to identify the mechanisms through which a phenotypic hit works.
