AffiASSAY® Ethanol Colorimetric & Fluorometric Assay Kit

The AffiASSAY® Ethanol Colorimetric & Fluorometric Assay Kit provides a precise and reliable method for measuring ethanol levels in various biological samples. This assay kit offers flexibility with options for both colorimetric and fluorometric detection, catering to the diverse needs of researchers in fields such as toxicology, pharmacology, and alcohol metabolism studies.

Key Features:

  • Dual Detection: Our assay kit allows for ethanol measurement using both colorimetric and fluorometric methods, offering flexibility based on experimental requirements.
  • High Sensitivity: The assay kit can detect low levels of ethanol, ensuring accurate quantification in biological samples.
  • Wide Application: The AffiASSAY® Ethanol Assay Kit is compatible with various sample types, including blood, serum, urine, saliva, and cell culture supernatants.
  • Quick and Easy: With a streamlined protocol, you can obtain results rapidly, saving time and resources in the laboratory.
  • Cost-Effective: Our kit provides an affordable solution for measuring ethanol levels, reducing experimental costs without compromising data quality.

Assay Principle:

The assay kit measures ethanol levels based on the enzymatic conversion of ethanol to acetaldehyde and hydrogen peroxide. The hydrogen peroxide generated reacts with a probe to produce a colorimetric or fluorometric signal, which is directly proportional to the ethanol concentration in the sample.


  • Toxicology Studies: Assess ethanol levels in biological samples to study the effects of alcohol consumption and exposure on cellular and physiological processes.
  • Pharmacological Research: Evaluate ethanol metabolism and clearance rates to understand drug-alcohol interactions and pharmacokinetics.
  • Alcohol Metabolism Studies: Investigate ethanol metabolism pathways and enzymatic activities in tissues and cells.

Kit Contents:

  • Ethanol Assay Buffer
  • Ethanol Enzyme Mix
  • Ethanol Probe
  • Microplate (96 wells)
  • Ethanol Standard
  • Detailed Protocol

AffiASSAY® Ethanol Colorimetric & Fluorometric Assay Kit Protocol:

[Please note that this protocol is a general guideline, and you should always refer to the specific instructions provided in the kit manual for accurate and detailed information.]

Materials Needed:

  • AffiASSAY® Ethanol Colorimetric & Fluorometric Assay Kit
  • Biological samples containing ethanol
  • Microplate reader capable of measuring absorbance and fluorescence
  • Pipettes and tips
  • Microcentrifuge tubes


Standard Curve Preparation:

  • Prepare a series of standard solutions containing known concentrations of ethanol standard provided in the kit.
  • Dilute the Ethanol Probe with Ethanol Assay Buffer to prepare the working solution.
  • Add the working solution to each standard solution to initiate the reaction.

Assay Plate Setup:

  • Label the microplate wells according to your experimental design, including wells for your samples, standards, and controls.
  • If using controls, prepare control samples without ethanol to serve as background controls.

Sample and Standard Addition:

  • Add 50-100 µL of your prepared samples and standard solutions to the appropriate wells on the microplate.
  • Ensure that the final reaction volume in each well is consistent.

Assay Reaction:

  • Add an equal volume of Ethanol Enzyme Mix to each well to initiate the reaction.
  • Incubate the microplate at the appropriate temperature (as specified in the kit instructions) for a recommended time to allow the enzymatic reactions to occur.

Colorimetric and Fluorometric Measurement:

  • After the incubation period, measure the absorbance and fluorescence of each well using a microplate reader.
  • For colorimetric detection, measure the absorbance at the appropriate wavelength.
  • For fluorometric detection, measure the fluorescence intensity using appropriate excitation and emission wavelengths.

Data Analysis:

  • Generate standard curves using the absorbance or fluorescence values obtained from the standard solutions.
  • Calculate the ethanol concentrations in your samples based on their respective absorbance or fluorescence readings and the standard curves.

Results Interpretation:

  • Interpret and analyze your results according to your research objectives.
  • Observe any variations or trends in ethanol levels among your samples.

Data Presentation:

  • Prepare your data for presentation or publication, and include the appropriate statistical analysis if required.


  • Dispose of all waste materials, including used assay components, according to your laboratory's safety protocols.
  • Always refer to the specific instructions provided with the AffiASSAY® Ethanol Colorimetric & Fluorometric Assay Kit for any kit-specific details or variations in the protocol.
  • Additionally, ensure that you adhere to the best practices and safety guidelines in your laboratory while conducting the assay.
