Product Description

8-Arm PEG-Thiol (8-Arm PEG-SH) is a multi arm PEG derivative with thiol groups at each terminal of the eight arms connected to one hexaglycerol core. The reactive free thiol, SH, sulfhydryl, or mercapto groups selectively react with maleimide and transition metal surface including gold, silver, etc. PEG-SH can be easily air oxidized to form S-S disulfide bonds, which can be reversed with reducing agents. It is a useful reagent for reversible PEGylation and PEG hydrogel.
