()-Biotinamidohexanoic acid hydrazide is widely used in biochemistry and molecular biology for labeling and detecting biomolecules. It serves as a versatile reagent in the preparation of biotinylated probes, which are essential for applications such as affinity chromatography, ELISA, and Western blotting. The hydrazide group allows for specific conjugation to aldehyde or ketone groups, making it useful for modifying carbohydrates, glycoproteins, and other biomolecules. This compound is particularly valuable in studying protein-protein interactions, cellular localization, and signal transduction pathways due to its high affinity for avidin or streptavidin. Its applications extend to diagnostic assays and research tools for identifying and isolating target molecules with precision.
