More Details

  • Alcoholic drinks are among the daily consumed beverages. Studies have shown heavy alcohol consumption may lead to various forms of liver diseases and to increased mortality rates. Quantitative determination of alcohol (ethanol, C2H5OH) has applications in basic research, drug discovery, clinic studies and in the alcoholic industry. Simple, direct and automation-ready procedures for measuring ethanol concentration are very desirable. BioAssay Systems EnzyChrom™ ethanol assay kit is based on alcohol dehydrogenase catalyzed oxidation of ethanol, in which the formed NADH is coupled to the formazan (MTT) chromogen. The intensity of the product color, measured at 565 nm, is proportionate to the ethanol concentration in the sample.

Does the assay react with methanol?

No, the assay does essentially not cross-react with methanol. Only at high concentrations (more than 100 mM methanol) will there be any significant nonspecific signal.
