Description
General Description
NH2-PEG-NH2 is a versatile homobifunctional PEG linker designed for crosslinking, polymer modification, and bioconjugation applications. The two terminal primary amine groups provide reactive sites for coupling with proteins, peptides, antibodies, nucleic acids, nanoparticles, fluorophores, polymers, and biomaterial surfaces.
The hydrophilic PEG spacer improves water solubility, flexibility, biocompatibility, and reduces steric hindrance during conjugation reactions. NH2-PEG-NH2 is frequently employed in hydrogel formation, polymer synthesis, surface functionalization, drug delivery systems, tissue engineering, and biomedical research.
