Polycaprolactone peg amino group (nh2-peg-pcl) can be used to modify proteins, polypeptides and other materials and small molecules with carboxyl (- COOH) or other active groups that can react with primary amine. Amino (- NH2) can easily form a stable amide bond with carboxyl, or form an amide bond with active ester (- NHS) at ph7-8.5. Polyethylene glycol can increase solubility and stability. Reducing the immunogenicity of peptides and proteins, it can also inhibit the nonspecific binding of charged molecules on the modified surface.
