VS-PEG-biotin

Vinylsulfone-Polyethylene glycol-biotin,VS-PEG-biotin/Vinylsulfone-PEG-biotin from ruixi.Vinylsulfone (VS) functionalized polyethylene glycol (VS PEG) is a thiol (-SH) group reactive PEG derivative that can be used to modify biomolecules or other materials via their available thiol groups. VS group react with free thiol groups easily in aqueous buffer between pH 6.5~8.5 at room temperature.
