High-Throughput Screening

Definition

High-throughput screening (HTS) is a method used in drug discovery and genetic engineering to rapidly test a large number of chemical compounds or genetic samples to identify those with a desired biological activity. It is a powerful tool that enables the efficient exploration of vast chemical libraries and genomic data to uncover potential therapeutic agents or identify gene functions.
