Malondialdehyde

Clinical relevance

Excessive oxidative stress can lead to degenerative damages in the body, such as oxidation of lipids, proteins, and DNA. The body has multiple endogenous biomarkers that can provide information about its physical condition, such as β-carotene, coenzyme Q10, glutathione, vitamin C and malondialdehyde (MDA), of which an increase in serum or plasma is a sign of oxidative stress.

MDA is an oxidation product of polyunsaturated fatty acids, and thus the laboratory diagnostic marker used for lipid peroxidation. Recent clinical studies show that the MDA concentration is elevated in patients with cystic fibrosis and other chronic respiratory diseases. The additional determination of the MDA level together with other parameters provides useful information about the degree of oxidative stress to optimise the therapy.

 

Product advantages

  • The marker for lipid peroxidation
  • Interference-free analysis
  • Reliable results

 

This Chromsystems assay allows the reliable chromatographic determination of malondialdehyde in one isocratic HPLC run with fluorescence detection. Sample preparation is based on an effective protein precipitation step followed by derivatisation. The resulting fluorophore is specific and detectable even at very low concentrations.
