Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Alcohol Dehydrogenase 3 (ADH3) were tested on 3 different plates, 8 replicates in each plate.The test principle applied in this kit is Sandwich enzyme immunoassay. This colorimetric assay is based on alcohol dehydrogenase catalyzed oxidation of ethanol, in which the formed NADH can convert a nearly colorless probe to an intensely colored product, which exhibits maximum absorbance at 440nm, which is proportional to the amount of ADH in the sample. Analysis of hepatic aldehyde dehydrogenase usually required inclusion of pyrazole, a n alcohol dehydrogenase inhibitor, in order to prevent interference of alcohol dehydrogenase in the assay. 2. PRINCIPLE OF THE ASSAY ADH ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-ADH antibody and an ADH-HRP conjugate. The assay sample and buffer are incubated together with ADH-HRP conjugate in pre-coated plate for one hour.

Alcohol dehydrogenase catalyzes the oxidation of ethanol to acetaldehyde using NAD as a co-substrate. This protocol describes a direct enzyme assay for determining alcohol dehydrogenase activity. When the exposure period was reduced, similar signs of toxicity were produced at nearly identical ethanol concentrations. To estimate the embryonic dose following a given waterborne ethanol concentration, a kinetic alcohol dehydrogenase (ADH) assay was adapted. Alcohol dehydrogenases (ADH) (EC 1.1.1.1) are a group of dehydrogenase enzymes that occur in many organisms and facilitate the interconversion between alcohols and aldehydes or ketones with the reduction of nicotinamide adenine dinucleotide (NAD to NADH). b) aerobic dehydrogenases (oxidases) they oxidize substrates, are electron transferring enzymesThe principle of the assay is that the substrate of the kit, p-nitrophenol maltoheptaoside (glucoseIt is soluble in water and alcohol and destroyed by acids.
