Peptide Libraries
Peptide library is a systematic combination of different peptides in large number. It is widely used in drug screening,

target validation, epitope mapping, vaccine development,and structure activity studies.There is an ever increasing

demand from large pharmaceutical companies due to the expanding interest in peptide drugs. Dgpeptides peptide

library services feature all attributes of peptide synthesis platform that enable our customers to synthesize larger

quantities of high purity peptides at lower cost than traditional methods.

Dgpeptides' peptide library services provide flexible selections of peptide purity levels(crude,desalt,>70%, >75%,

>80%, 85%, >90%, >95%, and >98%). Each peptide in the library undergoes rigorous quality control to avoid any

cross contaminants before delivery. All purified peptides are delivered with complete QC data including RP-HPLC, MS

report to ensure high quality.To meet the growing demand for high-throughput peptide library screening, Dgpeptides

has launched the Peptide Library Service, Which is a proprietary peptide synthesis platform utilizing Fmoc chemistry
to facilitate enhanced high throughput peptide screening platforms. Large numbers of peptides can be synthesized,

and lyophilized in parallel and delivered in a customizable format for an affordable price. All peptide QC is monitored by

a stringent Total Quality Management System.
