High-Throughput Screening (HTS)
High-Throughput Screening (HTS) — An automated method for testing large numbers of compounds or peptide sequences for biological activity using robotics and microplate assays.
What Is High-Throughput Screening?
High-throughput screening (HTS) is the automated testing of thousands to millions of compounds against a biological target in microplate format. For peptide drug discovery, HTS enables rapid identification of active sequences from large peptide libraries or optimization of lead compounds across concentration ranges.
HTS Format
- 384-well plates: Standard HTS format. 10-50 µL assay volume. 100,000+ compounds per day
- 1536-well plates: Ultra-HTS. 2-10 µL volume. Minimizes peptide consumption
- Detection: Fluorescence, luminescence, absorbance, or AlphaScreen readouts
- Automation: Robotic liquid handlers, plate readers, and data analysis software
Hit Validation
HTS hits require confirmation by dose-response curves, counter-screening against related targets (selectivity), and orthogonal assay formats to eliminate false positives from compound interference or aggregation.
