I. [Product Description]
VS-PEG-NHS (Vinylsulfone-Polyethylene Glycol-N-Hydroxysuccinimide) is a multifunctional organic intermediate, combining the specific coupling ability of the vinylsulfone group with the steric hindrance effect of the PEG chain. As an efficient bioconjugation catalyst, its NHS active ester can achieve amino-targeted modification under mild conditions and is widely used in the fields of biomaterials engineering such as protein coupling and nanocarrier functionalization.
