Relying on complete comprehensive and mature technology, we design different protection strategies and cutting methods according to the different lengths and different synthesis scales of target peptides and the characteristics of different amino acids, and adopt solid phase, liquid phase or combination methods to avoid impurities such as isomers and amino acid deletion to the greatest extent, and provide customers with high-quality linear peptides and cyclic peptides formed by amide bonds, double bonds and disulfide bonds.

We have developed chemical and enzyme-catalyzed methods to synthesize unnatural amino acids, C-, N-methylated amino acids and β-homo-amino acids, and synthesized dipeptides and pseudo-dipeptides according to the needs of different peptide chains, and improved product quality and raw peptide costs through this self-developed amino acid method.
