Description
Amine-PEG-Amine (NH₂-PEG-NH₂) is a linear bifunctional polyethylene glycol (PEG) linker featuring primary amine groups at both termini. These reactive amine groups readily couple with activated carboxylic acids, such as NHS esters, to form stable amide bonds. It is widely used as a crosslinking and conjugation reagent in bioconjugation, surface modification, and biomaterials applications due to its high reactivity, water solubility, and flexible PEG spacer.
