I. [Product Description]
NHS-PEG-VSN-N-hydroxysuccinimide ester-polyethylene glycol-vinyl sulfone is a bifunctional crosslinking agent with the high reactivity of both NHS ester and vinyl sulfone groups. It is suitable for the controlled coupling and modification of proteins, polypeptides, and biological macromolecules. As a high-performance organic intermediate, this compound improves water solubility and biocompatibility through the polyethylene glycol (PEG) segment and is widely used in the fields of biological material synthesis and nano-carrier preparation.
