Lipid Peroxidation (MDA) Assay Kit (Colorimetric/Fluorometric) (ab118970) provides a convenient tool for sensitive detection of malondialdehyde (MDA).
In the lipid peroxidation assay protocol, the MDA in the sample reacts with thiobarbituric acid (TBA) to generate a MDA-TBA adduct. The MDA-TBA adduct can be easily quantified colorimetrically (OD = 532 nm) or fluorometrically (Ex/Em = 532/553 nm). This assay detects MDA levels as low as 1 nmol/well colorimetrically and 0.1 nmol/well fluorometrically.
The MDA assay is also refered to as a TBARS assay.
Lipid peroxidation assay protocol summary:
- add TBA solution to samples and standards, incubate at 95ºC for 60 min, cool in ice bath for 10 min
- transfer to wells of microplate
- analyze with microplate reader
For higher sensitivity, precipitate with n-butanol, centrifuge, dry and resuspend pellet before analysis.
Chinese protocol available. See protocols section below.
For an alternative MDA assay, without the heating steps required in the TBARS assay, try MDA assay ab233471.
This product is manufactured by BioVision, an Abcam company and was previously called K739 Lipid Peroxidation (MDA) Colorimetric/Fluorometric Assay Kit. K739-100 is the same size as the 100 test size of ab118970.
Lipid peroxidation refers to the oxidative degradation of lipids. In this process free radicals take electrons from the lipids (generally in cell membranes), resulting in cell damage. Quantification of lipid peroxidation is essential to assess oxidative stress. Lipid peroxidation forms reactive aldehydes such as malondialdehyde (MDA) and 4-hydroxynonenal (4- HNE) as natural bi-products. Malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE) are often used as markers of lipid peroxidation, and to assay for oxidative damage / oxidative stress.
Review the oxidative stress marker and assay guide, or the full metabolism assay guide to learn about more assays for metabolites, metabolic enzymes, mitochondrial function, and oxidative stress, and also how to assay metabolic function in live cells using your plate reader.
Also see the popular 4-HNE Assay Kit ab238538 as an alternative marker of lipid peroxidation and oxidative stress.

相关性Lipid peroxidation refers to the oxidative degradation of lipids and is a well-defined mechanism of cellular damage. The formation of lipid peroxidation products leads to spread of free radical reactions leading to cell damage.
Hichor M et al. used the TBARS assay / MDA assay ab118970 to study the role of LXRs in the regulation of oxidative stress in peripheral nerves.They identified that in sciatic nerves in LXR knockout mice (LXRdKO), the MDA concentration was significantly increased, and that this was corrected by the treatment of mice with the anti-oxidant ROS scavenger N-acetylcysteine (NAC).
Ravarotto V et al. used Lipid Peroxidation Assay Kit ab118970 to assess oxidative stress in Fabry disease. They identified that MDA levels are higher in Fabry patients, indicating higher levels of oxidative stress.
The MDA concentration was measured in plasma from Fabry patients compared to healthy control patients. Data are shown ±SEM. *: p = 0.01.
