  • Target
    Ethanol
    Reactivity
    Chemical
    Application
    Biochemical Assay (BCA)
    Sample Type
    Serum, Plasma, Urine, Saliva
    Characteristics
    Sensitive and accurate. Detection limit 0.0008 vol % (140 μM or 8 ppm), linearity up to 0.1 % ethanol in 96-well plate assay.
    Convenient. The procedure involves adding working reagent, incuba- ting for 30 min and stropping reaction. No 37 °C heater is needed.
    High-throughput. Can be readily automated as a high-throughput 96- well plate assay for thousands of samples per day.
    Components
    Assay Buffer: 10 mL. NAD Solution: 1 mL. MTT Solution: 1.5 mL. Enzyme Mix: 120 µL. Stop Reagent: 12 mL. Standard: 1.5 mL 1% ethanol.
    Material not included
    Pipeting (multi-channel) devices. Clear-bottom 96-well plates (e.g. Corning Costar) and plate reader.
  • Application Notes
    Direct Assays: ethanol in serum, plasma, urine and saliva samples.
    Pharmacology: effects of drugs on alcohol metabolism.
    Comment

    1. This assay is based on an enzyme-catalyzed kinetic reaction. Addition of Working Reagent should be quick and mixing should be brief but thorough. Use of multi-channel pipettor is recommended.
    2. The following substances interfere and should be avoided in sample preparation: ascorbic acid, SDS (>0.2%), sodium azide, NP-40 (>1%) and Tween-20 (>1%).

    Protocol
    1. Calibration Curve. Prepare 0.1% alcohol Premix by mixing 25 µL 1% Standard and 225 µL distilled water. Transfer 10 µL standards into wells of a clear bottom 96-well plate. Samples: add 10 µL sample per well in separate wells. IMPORTANT: saliva samples should be diluted 10-fold in PBS prior to assay.
    2. Reaction. Spin the Enzyme Mix tube briefly before pipetting. For each well of reaction, prepare Working Reagent by mixing 80 µL Assay Buffer, 1 µL Enzyme Mix, 2.5 µL NAD and 14 µL MTT. Fresh reconstitution is recommended. Add 90 µL Working Reagent per well quickly. Tap plate to mix briefly and thoroughly. Incubate 30 min at room temperature. Add 100 µL Stop Reagent per well. Tap plate to mix.
    3. Read optical density at 565 nm (520-600nm).

  • Target
    Ethanol
    Background
    Quantitative determination of ethanol by enzymatic colorimetric (565nm) method.
    Procedure: 30 min.

    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. This 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.
