8-Arm PEG-VS

Synonyms: Eight-Arm polyethylene glycol-VS; Eight-Arm PEG-VS; Eight-Arm polyethylene glycol-Vinyl Sulfone

8-Arm PEG-VS is a multifunctional PEG reagent with eight sulfhydryl reactive vinyl sulfone groups. The VS at the end of the chain can react with sulfhydryl groups in aqueous buffers with a pH of 6.5 to 8.5 for site-specific PEG of peptides and proteins. 8-Arm PEG-VS has branching or comb-like structures and is commonly used in drug delivery systems. The molecular weight of the modified drug increases and is not easily eliminated by metabolism in the body. In addition, the dispersion and solubility of the modified drugs in vivo were improved. It can also modify the surface of biomaterials or form new biomedical materials.
