I. [Product Description]
WSW(WSWGPYS)-PEG-Biotin is an organic intermediate designed based on the hepatocyte-targeting polypeptide sequence. Through the efficient coupling of polyethylene glycol (PEG) and biotin, the molecular stability and targeting recognition ability are significantly enhanced. This compound can be used as a pharmaceutical intermediate in the field of bioconjugation technology. Its modular structure supports participation in complex synthetic reactions as a catalyst or a functional group.
