Creative Pegworks 8-Arm PEG-SH, MW 20k for 10 g
Supplier: Creative Pegworks PSB85210G
Description8-Arm PEG-Thiol is a multiarmed PEG derivative with thiol at each terminal of the eight arms. One hexaglycerol core connects all 8 arms through ether bonds. The reactive free thiol, SH, sulfhydryl, or mercapto selectively react with maleimide forming thioether bond. Thiol also PEGylates transition metal surface including gold, silver nanoparticles. PEG-SH can be easily air oxidized to form S-S disulfide bonds, which can be reversed with reducing agents. 8-Arm PEG-Thiol is a useful reagent for reversible PEGylation and forming PEG hydrogel.PropertiesMolecular weight: 8-Arm PEG MW refers to the MW of the entire PEG molecule. The MW of each arm is 1/8 of the MW indicated in the product name. MW of PEG was measured by MALDI-MS or GPC. PDI (polydispersity index) of our 8-Arm PEG is 1.02-1.06 with very narrow MW distribution.
