Peptide Library Services

A peptide library is a systematic combination of a large number of different peptides widely used for protein-related studies. Peptide libraries are in ever increasing demand due to the expanding interest in peptide drug and vaccine development.  GenScript offers two peptide library services: a standard peptide library for milligram level quantities, and a micro-scale peptide library for economical screening of microgram level peptide quantities.  Using our proprietary FlexPeptide™ technology, hundreds of peptides can be synthesized at low cost.

Peptide Library Specifications

To meet different purity demands for multiple applications, GenScript has developed two standard peptide library service packages: the crude peptide library and the purified peptide library.

Technology and Quality

Peptide libraries are synthesized using our proprietary PepHTS™ Peptide Library technology and undergo vigorous quality control to avoid cross-contamination prior to delivery. Click here to find out more about our Total Quality Management System.

Delivery Specifications

The typical peptide library consists of:

  • Lyophilized unbound peptides in 96-well plates or vials of 96-tube plates
  • COA, HPLC and MS data for all peptides
