BPG-1171 8-Arm PEG-SH, MW 10k-40k Inquiry

Synonyms: Eight-Arm polyethylene glycol-SH; Eight-Arm PEG-SH

8-Arm PEG-SH has a sulfhydryl group at each end of the eight arms attached to a glycerol core and is a multi-arm PEG derivative. The sulfhydryl groups at the molecular chain end selectively react with maleimides and transition metal surfaces (including gold, silver, etc.). PEG-SH is readily oxidized by air to form S-S disulfide bonds, which can be reversed by reducing agents. It is a useful reagent for reversible PEG and PEG hydrogels. 8-Arm PEG-SAA has branching or comb-like structures and is commonly used in drug delivery systems. In addition, the dispersion and solubility of the modified drugs in vivo were improved.
