I. [Product Description]
PEI-PEG-Biotin is a multifunctional organic intermediate formed by the covalent coupling of polyethylenimine (PEI), polyethylene glycol (PEG), and biotin. It combines the high loading capacity of PEI, the biocompatibility of PEG, and the high-specific binding properties of biotin. This compound can serve as an efficient catalyst carrier or pharmaceutical intermediate and is suitable for bioconjugation, nanomaterial modification, and the construction of targeted delivery systems.
