FITC-PEG-Biotin is a PEG chain conjugated with fluorescein isothiocyanate (FITC) and a biotin functional group. FITC is a fluorescent dye commonly employed for labeling biomolecules and surfaces due to its strong fluorescence properties. Biotin, a vitamin B7 derivative, serves as a high-affinity ligand for avidin and streptavidin proteins, enabling specific binding in various biological assays and detection methods. FITC-PEG-Biotin is widely used in the development of labeled biomolecules, fluorescent probes, and functionalized surfaces for applications such as immunoassays, fluorescence microscopy, and protein purification. This compound facilitates precise and controlled conjugation reactions, allowing for the design of customized probes and labeled biomolecules with enhanced stability, specificity, and versatility for diverse research and diagnostic purposes.
