4arm-PEG-SH is a multi-arm PEG with reactive free thiols, SH, cysteine, sulfhydryl, or mercapto group that selectively reacts with maleimide, vinyl sulfone and noble metal surfaces including gold, silver, etc.
4arm-PEG-SH can be easily air oxidized to form a dimer via a S-S disulfide bond, which can be reversed with reducing agents. It is useful for reversible PEGylation.
