Custom Peptide Synthesis

　

A Reliable supplier of high-quality synthetic peptide
GL Biochem (Shanghai) Ltd. is dedicated to provide highest quality peptides for university, institute, biotech company and pharmaceutical plant in the world. At the moment, the company has five production branches globally with total of 350 plus chemists directly involved in peptide synthesis, and additional 250 plus technicians in HPLC purification.

In addition to having well established manual synthesis techniques, GL Biochem also invests in units of Automated Multiple Peptide Synthesizers to support customers in peptidomimetics studies and drug discovery for milligram scale of a large number of related peptides and peptidomimetics. For more detailed information, please visit Peptide Array.

We have also developed different solution phase synthesis methodologies to meet customers' requirements for peptides in commercial scale.

Our monthly capacity reaches >10,000 purified custom peptides. Global market share has been over 60%. It possesses the biggest capacity with state-of-the art facilities in custom peptide in the world.
