I. [Product Description] 
OPSS-PEG-Catalase is a multifunctional organic intermediate. By virtue of the specific coupling property of the ortho-pyridyl disulfide bond (OPSS) with thiol groups and combined with the excellent water-solubility and stability of polyethylene glycol (PEG), it is widely used in bioconjugation reactions and the construction of catalytic systems. This compound can serve as an efficient catalyst carrier or pharmaceutical intermediate and has significant application value in the fields of enzyme immobilization and biomacromolecule modification.
