Overview
Ortho-pyridyl disulfide (OPSS) functionalized polyethylene glycol (OPSS PEG) is a thiol (-SH) group reactive PEG derivative that can be used to modify biomolecules or other materials via their available thiol groups. Ortho-pyridyl disulfide reacts with thiol group to form a stable disulfide bond while a thiol pyridyl group is released.
