High-throughput Screening
A scientific methodology that enables rapid, automated testing of large numbers of chemical or biological samples against specific targets to identify active compounds, materials, or conditions.
High-throughput Screening (HTS)
High-throughput screening represents a fundamental paradigm shift in how scientists approach experimental discovery, combining laboratory automation with sophisticated data analysis to accelerate research outcomes.
Core Principles
The foundation of HTS rests on three key pillars:
