Mal-PEG-CH2CO2H is a thiol-reactive polyPEG with a carboxyl terminus. Carboxyl groups react specifically with thiol groups to form covalent C-S bonds enabling bioconjugation with thiol-bearing molecules. The coupling between the carboxyl group and the amine occurs through a condensation reaction and produces an amide bond.
