Peptide Library Quotation

A peptide library is a systematic combination of a large number of different peptides widely used in drug screening, target validation, epitope mapping, vaccine development, and structure-activity studies. Peptide libraries are in ever increasing demand due to the expanding interest in peptide drug and vaccine development. GenScript peptide library services feature peptide synthesis via our proprietary FlexPeptide™ technology, which allows for rapid high-throughput parallel peptide synthesis. Our peptide synthesis platform allows us to synthesize hundreds of peptides at low cost.

Technology

To meet the growing demand for high-throughput peptide library screening, GenScript developed its PepHTS™ Peptide Library Service. PepHTS™ is a proprietary peptide synthesis platform utilizing fmoc chemistry, for the synthesis of enhanced high-throughput peptide screening platforms. Hundreds of peptides (up to 10,000 per month) can be synthesized and lyophilized in parallel, and delivered in a customizable format for an affordable price.

Quality

Each peptide synthesized by GenScript's peptide library service undergoes rigorous quality control to avoid cross contamination prior to delivery. All purified peptides are delivered with complete QC data including RP-HPLC, MS, and COA reports to ensure high quality. Peptide quality is monitored through our stringent Total Quality Management System.

Design

GenScript provides six free peptide library design tools to help you generate the peptide library that best fits your research design.



Easy Quotations

GenScript also provides a secure, peptide library online quotation system for your convenience. Or you can email us with your peptide library quote request at peptide@genscript.com.
