Introduction

Oxidative stress can lead to toxic effects by generating peroxides and free radicals that can damage all cell components, including proteins, lipids, and DNA. Lipid peroxidation is a well-known mechanism of cellular damage in both animals and plants and has been associated with cardiovascular diseases, atherosclerosis, diabetes, liver disorders, and inflammatory rheumatic diseases. Thiobarbituric Acid Reactive Substances (TBARS) are byproducts of lipid peroxidation which are caused by reactive oxygen species and other oxidative mechanisms. Malondialdehyde (MDA) is the major TBARS and is widely used as an indicator of oxidative stress in cells and tissues.

The RayBio Lipid Peroxidation (MDA) Assay Kit provides a simple, reproducible, and standardized tool for assaying lipid peroxidation in serum, plasma, cell or tissue lysates, urine, or other body fluid samples. The assay utilizes the reaction of MDA with thiobarbituric acid (TBA), producing a pink-colored product. The intensity of the pink color, measured at 532 nm, is directly proportional to the concentration of MDA in the sample. The MDA standard or unknown samples containing MDA are first reacted with TBA under high temperature (95°C) and acidic conditions. The MDA-TBA adduct is then measured colorimetrically at 532 nm. The MDA content in unknown samples is determined by comparison with the MDA standard curve.

  • Spectrophotometric microplate reader capable of reading at 532 nm
  • Analytical balance

Assay Procedure Summary

Prepare and mix all reagents thoroughly before use. Each MDA-containing sample and standard should be assayed in duplicate. High content MDA samples can be further diluted for analysis.

  1. Pipette 100 µl of samples or prepared MDA series standards (see Pre-Assay Preparation, B) to each microcentrifuge tube.
  2. Add 100 µl of the SDS Solution to each sample and the MDA standards. Mix thoroughly and quick spin, Incubate samples for 5 minutes at room temperature.
  3. Add 250 µl of prepared TBA Reagent (see Pre-Assay Preparation, A-3) to each sample and standard. Mix thoroughly then incubate at 95°C for 60 minutes.
  4. Put all tubes on ice and incubate for 5 minutes.
  5. Centrifuge all tubes at 1600 x g for 10 minutes.
  6. Transfer 200 µL of supernatant from each sample and the MDA standards to a 96 well microplate. Read the absorbance at 532 nm immediately.

    Working with both tissue lysate and effluent. Protocol is very straightforward. Only time consuming portion is that samples need to be prepared in microcentrifuge tubes instead of a 96-well plate as it has a 90ºC incubation, so it is not time-effective if you plan to run a lot of samples. Otherwise it's a good assay!
