HOOC-PEG-NH2 (MW 2000)

Description

HOOC-PEG-NH2 MW 2000 HOOC-PEG-Amine MW 2000 is a heterobifunctional PEG crosslinker that can be used to attach functional PEG to biomolecules, particles, and other surface materials. The carboxyl group reacts with the amine group to form a stable amide bond. It can also react with the hydroxyl group to form an unstable ester bond. On the other hand, the amine group can be used to react with many amine-reactive groups, such as succinimidyl NHS esters, aldehydes, etc.
