The synthesis technology of polypeptides has important application value in drug development, bioengineering and life science research. Peptide drugs with specific functions and activities can be synthesized through peptide synthesis, such as antimicrobial peptides, anti-tumor peptides and so on. The development of polypeptide synthesis technology enables scientists to better study and utilize the biological functions of polypeptide molecules, contributing to the development of human health and life sciences.

The specific steps of peptide synthesis are as follows:

(1) Design the synthesis scheme according to the peptide sequence and select the appropriate amino acid protection group.

(2) Use solid-phase synthesis or liquid-phase synthesis to synthesize polypeptides. In solid phase synthesis, the first amino acid is fixed to the solid phase carrier, and then the next amino acid is added one by one, and the reaction is carried out. Liquid phase synthesis is the process of dissolving amino acids in solvents to form peptides step by step.

(3) Prepare activator to remove amino acid protective group.

(4) The steps of peptide bond formation and protective group removal are repeated until a complete polypeptide molecule is synthesized.

(5) Purification and analysis of the synthesized peptides, such as high performance liquid chromatography (HPLC), mass spectrometry (MS), etc.

* Modification types: up to 300+ extensive modification for conventional peptide synthesis, up to 30+ modification for Fast peptide synthesis and Rush peptide synthesis.
