Description

Thiol-PEG-Thiol (HS-PEG-SH, SH-PEG-SH) is a linear homobifunctional PEG with two reactive free thiol. SH, sulfhydryl, or mercapto groups selectively react with maleimide and transition metal surface including gold, silver. HS-PEG-SH undergoes air oxidation and polymerization forming S-S disulfide bonds. Disulfide bond is reversible with reducing agents such as TECP. It is a useful reagent for reversible crosslinking PEGylation. HS-PEG-SH can crosslink two molecules containing maleimide. Thiol is very useful in thiol-ene reaction to react with acrylate, norbornene etc. Bifunctional thiol PEG is a common crosslinker in preparing hydrogels.
