High-throughput screening

Definition

High-throughput screening (HTS) is a method used to rapidly evaluate a large number of compounds or biological samples for their potential activity against specific targets, such as proteins or cells. This approach allows researchers to identify active substances, prioritize them for further study, and significantly speed up the process of drug discovery and toxicological assessment.
