Peptide Drug Discovery

High-Throughput Screening for Peptide Therapeutics


High-throughput screening is a proven approach in drug discovery to identify candidate drugs. Tango Biosciences’ phage display platform and custom peptide libraries are ideally suited to rapidly identify initial hits for any target. Our affinity maturation phase can augment binding to maximize affinity and selectivity.

We offer several phage display libraries featuring varying copy number, linear and cyclic peptides, and peptide length, along with custom peptide library solutions to initiate discovery for your next program.
