High-throughput screening

Definition

High-throughput screening is a method used to quickly conduct millions of chemical, genetic, or pharmacological tests to identify active compounds, antibodies, or genes that modulate a particular biomolecular pathway. This approach allows researchers to rapidly assess multiple samples and gather vast amounts of data, making it an essential tool in drug discovery and molecular biology.
