QuantiChrom™ Ethanol Assay Kit
Datasheet PDF  MSDS/Bulk Order


Application
For quantitative determination of ethanol and alcohol metabolism.

Key Features
Sensitive and accurate. Detection range 0.04 - 4% alcohol in 96-well plate assay.

Convenient and high-throughput. The procedure involves adding a single working reagent, incubation for 8 min, adding a Stop Reagent, and reading the optical density. Can be readily automated as a high-throughput 96-well plate assay for thousands of samples per day.

Versatility. Assays can be executed in 96-well plate or cuvet.

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) finds applications in basic research, drug discovery, clinic studies and winery. Simple, direct and automation-ready procedures for measuring ethanol concentration are very desirable. BioAssay Systems’ QuantiChrom™ ethanol assay kit is based on an improved dichromate method, in which dichromate is reduced by ethanol to a bluish chromic (Cr3+) product. The intensity of color, measured at 580 nm, is a direct measure of the alcohol concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples and exhibits high sensitivity.

1. We are working with a very small murine blood sample (20 μl) and cannot safely remove more than this for our purposes. Will your assay work with such a small sample? Would this require any special methods?



Serum samples will be diluted 3-fold during deproteination. You have to add water to give 100 μL sample for the assay. The ethanol concentration should be 0.04% or higher in the diluted sample, or (>0.2%) in the initial serum sample, in order to be quantified accurately. Our enzyme based ethanol assay (ECET-100), which is more sensitive, might be a better option for you.

2. Does glucose interfere with the assay?



Yes, glucose and other compound containing hydroxyl groups (sugars, glycerol, etc.) do interfere with the assay. Samples containing high amounts of glucose should be pretreated with our saccaride removal kit (DSRK-500). Our enzyme based ethanol assay (ECET-100), which is more specific, is the better option for such samples.
