Overview

Biomarker discovery is becoming increasingly popular for developing novel drugs and immunotherapeutics. Peptide libraries are offered at different purity levels to ensure all research applications are met.

GenScript offers two peptide library services: standard peptide libraries and micro-scale peptide libraries. Each of these services can be purchased crude (approximately 30% purity) or purified.
