Lipid peroxidation is characterized by the oxidative degradation of unsaturated fatty acids, phospholipids, glycolipids, cholesterol esters and cholesterol. Malondialdehyde (MDA) is one of the most commonly used biomarkers for lipid peroxidation. Measurement of MDA has historically relied on a reaction with thiobarbituric acid (TBA) to generate a product that can be measured colorimetrically or fluorimetrically. However, TBA assay has quite a few limitations. (1). The reaction is not specific to MDA. (2). TBA-MDA reaction need be run under acidic conditions. (3). The assays need be run under high temperature, commonly at 90-100 ºC. The commercial TBA-based MDA assays are extremely tedious to run due to these limitations. This Cell Meter™ Colorimetric Lipid Peroxidation (MDA) Quantitation Kit offers the most rapid and convenient method to measure MDA without the TBARS heating steps. MDA Blue™ reacts with MDA to generate a blue color product which is measured at 695 nm with absorbance microplate reader. This assay is very fast and specific to MDA with little interference from other aldehydes.

Example protocol


Protocol summary

  1. Prepare and add MDA standards and/or test samples (50 µL)
  2. Prepare and add MDA Blue™ (10 µL)
  3. Incubate at room temperature for 10 - 30 minutes
  4. Add reaction solution (40 µL)
  5. Monitor OD increase at 695 nm

Important notes
Thaw all the kit components at room temperature before starting the experiment.


Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.

MDA standard stock solution (100 mM):
Add 100 µL of ddH2O into MDA Standard (Component C) and mix them well. Note: The unused MDA stock solution should be stored at -20°C in single use aliquots.


MDA standard

For convenience, use the Serial Dilution Planner:

Add 4 μL of MDA standard (100 mM) into 996 μL of Dilution Buffer (Component B) to get MDA standard solution (400 μM). Then perform 1:2 serial dilutions in dilution buffer to get 200, 100, 50, 25, 12.5, 6.25 and 0 μM serially diluted MDA standards.

MDA assay

  1. Add 50 µL of MDA standard, blank control, and test samples to clear bottom 96-well microplate (As shown in Table 1 and Table 2).

  2. Add 10 µL/well of MDA Blue™ (Component A) into each well of MDA standard, blank control and test samples. Note: For a 384-well plate, add 25 µL of sample, 5 µL of MDA Blue™ solution into each well. Note: Please aliquot Component A into single use size and store unused at -20oC and avoid light.

  3. Incubate the reaction at room temperature for 10 - 30 minutes, protected from light.

  4. Add 40 µL of Reaction Solution (Component D) to make the total assay volume of 100 µL/well. Note: For a 384-well plate, add 20 µL of Reaction Solution (Component D) to make the total assay volume of 50 µL/well.

  5. Monitor absorbance increase with an absorbance plate reader with path-check correction at OD of 695~700 nm.
