Featured Products
HABA (CAS 1634-82-8), chemically known as 4'-hydroxyazobenzene-2-carboxylic acid, is a small molecule commonly used as a chromogenic reagent in biomedical research. It interacts specifically with proteins such as avidin and streptavidin, forming complexes detectable by changes in absorption spectra, thus serving as an indicator in biotin quantification assays. Due to this selective binding property, HABA assays facilitate the study of protein-ligand interactions, bioconjugate characterizations, and diagnostic assay development.
