Description

4-Arm PEG-OPSS is a multiarm PEG derivative with OPSS at each terminal of the four arms. OPSS stands for orthopyridyl disulfide. OPSS also called PDP, standing for 3-(2-pyridyldithio) propionic acid. The orthopyridyl disulfide or pyridyldithio functional group selectively reacts with free thiol, SH, sulfhydryl or mercapto to form a reversible disulfide bond. Under certain conditions, OPSS generates free thiol in solution for direct PEGylation of gold nanoparticles.
