Carboxyl group forms stable amide bond with amino group and ester bond with hydroxyl group. The active ester reacts with primary amine group at ph7-8.5 to form stable amide bond. Polyethylene glycol can increase the solubility and stability of drugs, reduce the immunogenicity of peptides and proteins, and inhibit the nonspecific binding of charged molecules on the modified surface. It can modify proteins, peptides and other small molecular materials. It is widely used in pharmaceutical research, drug release, new nano materials research and cell culture. It has become a research trend in ligand research of active compounds, peptide synthesis carrier, polymer graft compound, polyethylene glycol coating and modification functionalization of new materials.
