High-throughput screening

Definition

High-throughput screening (HTS) is a method used in drug discovery and biotechnology that allows researchers to quickly test thousands of compounds for their ability to affect a specific biological target. This technique leverages automation, robotics, and data analysis to streamline the process of identifying potential therapeutic agents, making it a crucial tool in the development of targeted treatments for diseases such as cancer.
