This compound is a biotin derivative with an aminoethylamide linker, utilized in biochemical and molecular biology research for preparing biotinylated conjugates. The biotin moiety enables high-affinity binding to avidin or streptavidin, facilitating detection and purification in techniques such as immunoassays (e.g., ELISA), Western blotting, and fluorescence microscopy. The terminal primary amine allows for covalent attachment to proteins, peptides, antibodies, or other biomolecules, making it ideal for labeling and studying cellular processes, protein-protein interactions, and targeted delivery systems. It exhibits low toxicity and is suitable for in vitro applications.
