4arm-PEG-SH (1 gram)
Catalog #: 4A-PEGSH-20K-1g
mol wt: average Mn 20,000
Linear Formula C(CH2O(CH2CH2O)nCH2CH2SH)4
polymer architecture shape: 4-arm
functionality: homofunctional
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.
This product may be used for:
bioconjugation
drug delivery
PEG hydrogel
crosslinker
surface functionalization
