We, GL Biochem , a leading manufacturer and supplier of amino acids, peptides and antibodies, has accumulated many technical knacks since our establishment in 2008. We have a group of experts armed with more than thirteen years’ experience in lab, who are still working on exploiting new structures of amino acids and peptides and their new synthesis technologies.

Our products include catalogue and custom amino acids, peptides and antibodies. Our service contains IR、NMR、MS、HPLC spectrogram as required, COA(Certificate of Analysis) of products, molecular structure of products. And if you have problems involve solubility, chemical properties, molecular structure control of products, we could help you discuss with our experts.
