VS-PEG-VS, MW 1k-20k
Cat No.: BPG-0628
4.5 
VS-PEG-VS has two identical with a thiol reactive vinylsulfone groups. Vinyl sulfone is mainly used as an intermediate for a variety of dyes, and can also be used as an intermediate for pharmaceutical chemicals. Homobifunctionalized PEG derivatives have wide applications in peptides, proteins, lipids, other small molecules and surface modifications. Drug PEGylation can alter its dispersity and solubility in aqueous solutions. PEG modification can create a spatial barrier around the drug, reduce the enzymatic hydrolysis of the drug, avoid the rapid elimination of kidney metabolism, and allow the drug to be recognized by cells of the immune system.
