I. [Product Description]
Mal-PEG-VS (Maleimide-Polyethylene Glycol-Vinyl Sulfone) is a bifunctional crosslinking agent with both organic intermediate and bioconjugation application values. Its maleimide group can specifically bind to thiols, and the vinyl sulfone group can efficiently couple to amino or hydroxyl groups. The PEG chain enhances water solubility and reduces immunogenicity. It is suitable for cutting-edge fields such as protein modification, nanoparticle carrier preparation, and biosensor development.
