I. [Product Description]
SS-PEG-Biotin is a functionalized organic intermediate containing a disulfide bond (SS), a polyethylene glycol (PEG) chain, and a biotin modification. It combines bioorthogonal reactivity with excellent water solubility. The disulfide bond enables reductive-responsive cleavage, the PEG chain enhances biocompatibility, and the biotin group provides specific binding ability. It is widely used in fields such as targeted carrier construction, bioconjugation reactions, and catalyst loading.
