Ortho-pyridine disulfide PEG, mPEG-OPSS

Orthopyridyl disulfide functionalized polyethylene glycol (mPEG-OPSS) is a thiol (-SH) reactive PEG derivative that can be used to modify protein, peptide or any other surfaces via available thiol (sulfulhydryl) group in cysteine residues to generate a cleavable disulfide bond. OPSS PEGs react with thiol groups at pH 5.0~6.5.
