Product Description

Poly(L-lactide-co-glycolide)-block-PEG-OPSS (PLGA-PEG-OPSS) is a functional amphiphilic block copolymer which has orthopyridyl disulfide group at PEG end. Orthopyridyl disulfide or pyridyldithio functional group can selectively reacts with free thiol, SH, sulfhydryl or mercapto to form a oxidation, reduction reversible disulfide bond. Micelles or nanoparticles from PLGA-PEG-OPSS can be modifed via OPSS for targeted drug delivery.
