TBARS Malondialdehyde Oxidative Stress Assay

Our TBARS Malondialdehyde Oxidative Stress Assay is a tool for the direct quantitative measurement of MDA in biological samples formed from lipid peroxidation due to oxidative stress. Oxidative modification of lipids occurs with aging and various diseases, especially diabetes and kidney disease. Because lipid peroxidation is a complicated process, we recommended that multiple oxidative stress assays be used in conjunction, such as Exocell’s Thiol Oxidative Stress Assay.

Our kit uses thiobarbituric acid which forms an adduct with MDA. The samples are first reacted with TBA at 75˚C. After the overnight incubation the standards and samples are read either fluorometrically or spectrophotometrically. The MDA content in the samples is determined by linear regression comparison of the standard curve. The sensitivity of measuring Thiobarbituric Acid Reactive Substances (TBARS) has made this assay the method of choice for screening and monitoring lipid peroxidation.

The TBARS Malondialdehyde Oxidative Stress Assay kit contains all of the components and reagents you need to conduct a fluorescence assay for MDA of any animal species in up to 89 single urine or cell free liquid samples (plasma, serum, cell culture supernatant, etc…). Directions for an optical assay are included and may be conducted by using your own clear plate.
