Biotin-XX hydrazide is widely used in biochemical and molecular biology research for labeling and detecting biomolecules. It is particularly valuable for conjugating with aldehydes or ketones, enabling the biotinylation of glycoproteins, carbohydrates, and other aldehyde-containing compounds. This biotinylation process allows for efficient detection and purification using streptavidin or avidin-based systems, which are commonly employed in techniques like ELISA, Western blotting, and flow cytometry. Additionally, it is utilized in glycan analysis and glycoproteomics to study post-translational modifications and glycosylation patterns. Its hydrazide group ensures selective and stable conjugation, making it a reliable tool for probing and analyzing complex biological systems.
