I. [Product Description] 
Biotin-PEG-SPDP is a multifunctional organic intermediate. Through the high-affinity binding properties of biotin, the excellent water solubility and stability of the PEG chain, and the controllable disulfide bond cleavage mechanism of the SPDP group, it enables precise bioconjugation of biomolecules. This compound has significant application value in fields such as drug delivery systems, modification of polymer materials, and enzyme immobilization. It can also serve as an efficient catalyst carrier to enhance reaction efficiency.
