Introduction

Solid Phase Peptide Synthesis (SPPS)

Solid-phase synthesis is a process of repeatedly adding amino acids, usually from the C-terminus to the N-terminus. First, the C-terminus of the first amino acid is connected to the solid-phase carrier through a covalent bond, and then the N-terminus of the amino acid is used as the starting point for synthesis to form peptide bonds with other activated amino acids. This process is repeated continuously to obtain the target polypeptide. At present, we are using a synthetic method based on Fmoc.

Liquid Phase Peptide Synthesis (LPPS)

Liquid phase synthesis is a traditional method of peptide synthesis. We mainly use this method to synthesize large-scale peptides, polymeric peptides and difficult peptides.
