mPEG-COOH is one of carboxylic acid (-COOH) functionalized polyethylene glycol derivatives that can be used to modify proteins, peptides, particles and other materials with their free acid group. Carboxylic acid groups react readily with amine groups to form stable amide bond. Acid functionalized PEG has broad applications in the field of medical device modification, biomolecule pegylation and particle surface functionalization.
