Poly(ethylene glycol) methyl ether thiol (mPEG-SH, mPEG-Thiol, Methoxy PEG Thiol) is linear monofunctional PEG with a reactive free thiol, SH, cysteine, sulfhydryl or mercapto group. Thiol selectively reacts with maleimide and novel metal surface including gold, silver, etc. mPEG-SH can be easily air oxidized to form a dimer via a S-S disulfide bond. The disulfide bond is reversible with reducing agents such as TECP or glutathione. PEG thiol reagents are thus useful for reversible PEGylation.
