Biotin-PEG-Biotin（Cat No.:I043457）is a bifunctional reagent that consists of two biotin molecules connected by a polyethylene glycol (PEG) linker. The biotin groups enable strong, specific binding to avidin or streptavidin, which are often used in biotechnological applications like protein purification, immunoassays, and diagnostics. The PEG linker enhances the solubility and stability of the compound, reducing steric hindrance between the biotin groups and the target molecules. Biotin-PEG-Biotin is commonly used in molecular biology for crosslinking, improving assay sensitivity, and facilitating the detection and isolation of biotinylated proteins or nucleic acids.
