I. [Product Description]
Biotin-PEG-Mal (Biotin-Polyethylene Glycol-Maleimide) is a multifunctional organic intermediate widely used in the fields of bioconjugation and molecular probe construction. Its core value lies in achieving specific thiol coupling through the maleimide group. Combining the excellent water solubility of the PEG chain and the high affinity of biotin, it provides an efficient cross-linking solution for the preparation of pharmaceutical intermediates and catalytic reaction systems.
