Bis-NHS PEG

The NHS-PEGn-NHS series, exemplified by NHS-PEG12-NHS, is a homobifunctional crosslinker specifically designed for conjugating amine-containing molecules such as proteins, peptides, and nanoparticles through stable amide bond formation. This reagent offers high reactivity, tunable PEG spacer length (n), and efficient crosslinking capability for constructing biomolecular complexes. Key advantages include rapid reaction kinetics under physiological conditions and enhanced water solubility.
