azure b

Azure B (Azure B chloride) is a cationic dye and the major metabolite of Methylene blue. Azure B is a selective, and reversible inhibitor of MAO-A (IC50s: 11 and 968 nM for recombinant human MAO-A and MAO-B).

Azure B eosinate is a versatile dye used extensively in biological experiments to assist researchers in observing cell structures, tracking biomolecules, evaluating cell functions, distinguishing cell types, detecting biomolecules, studying tissue pathology, and monitoring microorganisms. Its applications span basic scientific research to clinical diagnostics. In addition to these scientific uses, dyes are crucial in traditional areas like textile dyeing, as well as in emerging fields such as functional textile processing, food pigments, and dye-sensitized solar cells.

Azure C, the product of sequential enzymatic oxidation of Methylene blue (MB) or Azure B (AB), serves as the substrate of horseradish peroxidase (HRP) [1] [2].
