Overview

Cyclic peptides are commonly used for diagnostics and vaccine development. Compared with straight-chain peptides, cyclic peptides have better conformational stability, target affinity, and improved selectivity. GenScript now offers compressive types of cyclic peptides up to kg levels to help accelerate your peptide therapeutic development projects.
