Carboxylated polyethylene glycol (ho-peg-cooh) can be used to modify proteins, peptides and other materials with active groups. Carboxyl groups can easily form stable amide bonds with amino groups or ester bonds with hydroxyl groups. Polyethylene glycol can increase solubility and stability, reduce the immunogenicity of peptides and proteins, and inhibit the nonspecific binding of charged molecules to modify the surface. This material has a wide range of applications in the field of medical device modification, biomolecular modification and particle surface functionalization.
