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. Chinapeptides peptide library services feature all attributes of
proprietaryFlexPeptideTM technology, which has materialized into a rapid high-throughput parallel
peptide synthesis platform that enable our customers to synthesize larger quantities of high purity
peptides at lower cost than traditional methods.
Chinapeptides' 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, Chinapeptides 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.
In addition, Chinapeptides provides an instant peptide library online quotation system to offer you
further efficiency and convenience.
