Thermo Scientific Pierce HABA is 4'-hydroxyazobenzene-2-carboxylic acid, a simple reagent that enables spectrophotometric (colorimetric) estimation of biotinylation levels of labeled proteins and other molecules.
Determine the molar ratio of biotin incorporated into a protein using the HABA-Avidin method. HABA dye (4'-hydroxyazobenzene-2-carboxylic acid ) binds to avidin to produce a yellow-orange colored complex which absorbs at 500nm. Free biotin will displace the HABA dye and cause the absorbance to decrease. A standard curve can be established using the free biotin to estimate the number of moles of biotin incorporated after biotinylating a protein. View online HABA Calculator.
