I. [Product Description]
VS-PEG-Biotin (Vinylsulfone-Polyethylene Glycol-Biotin) is a multifunctional organic intermediate. The vinylsulfone group has high reactivity and can specifically bind to sulfhydryl or amino groups, which is suitable for bioconjugation and material surface modification. This compound enhances water solubility and biocompatibility through a precisely designed PEG segment, and at the same time combines the high-affinity property of biotin, showing unique application value in catalyst loading and labeling technology.
