HOOC-PEG-NH2 (MW 3400)

HOOC-PEG-NH2 (MW 3400) [HOOC-PEG-Amine (MW 3400) ] is a heterobifunctional PEG crosslinker designed for attaching functional PEG to biomolecules, particles, and various material surfaces. The carboxyl group reacts with amines to form a stable amide bond and can also form an unstable ester bond with hydroxyl groups. Meanwhile, the amine group can react with numerous amine-reactive groups such as succinimidyl NHS esters, aldehydes, and more.
