High-throughput screening assays

Definition

High-throughput screening assays are automated techniques used to rapidly evaluate thousands to millions of biological compounds for their potential effects on a specific biological target, such as an enzyme. These assays enable researchers to efficiently identify lead compounds that can inhibit or enhance enzymatic activity, ultimately aiding in drug discovery and development. By allowing for large-scale experimentation, high-throughput screening enhances the ability to study enzyme kinetics and the mechanisms of inhibition.
