PEG di(NHS), Mp 2000

PEG Di(NHS) (NHS-PEG-NHS) is a bifunctional PEG derivative with N-hydroxysuccinimide (NHS) ester groups on both termini, designed for amide bond formation with primary amines. This highly reactive structure enables efficient crosslinking of proteins, peptides, and biomaterials, making it useful for bioconjugation, hydrogel formation, and surface modification.

Applications:
Protein Crosslinking & PEGylation: Forms amide bonds with lysine residues, enhancing solubility and stability of biomolecules.
Hydrogel & Polymer Synthesis: Crosslinks amine-functionalized polymers, improving mechanical properties and biocompatibility.
Surface Coating & Biocompatibility: Reduces fouling on biosensors, implants, and nanoparticles.
Drug Delivery & Targeted Therapy: Functionalizes drug carriers for enhanced therapeutic performance.
