I. [Product Description]
WSW(WSWGPYS)-PEG-Epoxides is a polypeptide-polyethylene glycol-epoxide conjugate with liver-targeting function. As a high-purity organic intermediate, it is widely used in the fields of targeted carrier construction and functional modification. Its core value lies in enhancing water solubility and biocompatibility through the PEG segment, while the epoxide group provides high-efficiency chemical coupling activity, which is suitable for the development of catalytic systems and the assembly of complex molecules.
