Lipid Peroxidation (MDA) Assay Kit (Colorimetric)

Product details

How the assay works

In this Lipid Peroxidation (MDA) Assay, the MDA Color Reagent reacts with MDA to generate a blue color product which is measured at 695 nm with absorbance microplate readers.
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.

Running an MDA assay has historically relied on a reaction with thiobarbituric acid (the TBARS assay) to generate a product that can be measured colorimetrically at 532 nm or fluorimetrically at Ex/Em = 530/550 nm.

However, the TBARS assay has quite a few limitations:
- the reaction is not specific to MDA,
- the TBA-MDA reaction needs be run under acidic conditions,
- the TBARS assay needs be run under high temperature, commonly at 90-100 °C.

Lipid Peroxidation (MDA) Assay Kit (Colorimetric) protocol summary:

- add samples and standards to wells
- add MDA color reagent and incubate for 10-30 min at room temp
- add reaction solution and incubate for 30-60 min at room temp
- analyze with microplate reader
