I. [Product Description]
WSW(WSWGPYS)-PEG-OPSS is a liver-targeting polypeptide conjugated organic intermediate that enables controllable bioconjugation through the ortho-pyridyl disulfide (OPSS) group. Its polyethylene glycol (PEG) segment significantly enhances water solubility and biocompatibility. This compound, serving as a high-precision catalyst and functional pharmaceutical intermediate, is suitable for the construction of targeting carriers and the directional modification of biomolecules.
