I. [Product Description]
Biotin-PEG-SS (Biotin-Polyethylene Glycol-Disulfide Bond) is a multifunctional organic intermediate that combines the high-affinity properties of biotin with the biocompatibility of the PEG chain. It can be used as a pharmaceutical intermediate or catalyst in targeted molecular coupling systems. Its disulfide bond structure supports controlled cleavage and is suitable for constructing responsive nanocarrier drug delivery systems or modifying the interface of biosensors.
