Product Description
Thiol-PEG-Thiol (HS-PEG-SH) is a linear homobifunctional PEG with two reactive free thiol, SH, sulfhydryl, or mercapto groups that selectively react with maleimide and transition metal surface including gold, silver, etc. HS-PEG-SH can be easily air oxidized and polymerized via S-S disulfide bonds, which can be reversed with reducing agents. It is a useful reagent for reversible crosslinking PEGylation.
