Biochempeg - Model mPEG-SH - High Purity Polyethylene Glycol (PEG)

Uses: Applicated in medical research, drug-release, nanotechnology and new materials research, cell culture. In the study of ligand, polypeptide synthesis support, a graft polymer compounds, new materials, and polyethylene glycol-modified functional coatings and other aspects of the active compound. Methoxy PEG Thiol (mPEG-SH) is a linear monofunctional PEG, which has a free thiol group at one end which can selectively reacts with maleimide and transition metal surface including gold, silver, etc.  mPEG SH is commonly used to modify gold or sliver nanoparticles. Also, it can be easily oxidized by air through S-S disulfide bonds to form dimers, which can be reversed with reducing agents.
