- Detection method: Colorimetric method
Detection principle
MDA in the catabolite of lipid peroxide can react with thiobarbituric acid (TBA) and produce red compound, which has a maximum absorption peak at 532 nm.

Images
The level of MDA was significantly lower (P<0.001) in NPCoQ10 groups and even lower in N-NPCoQ10 group.
Z Liu et al found that the usage of N-NPCoQ10 nano-particle can help for transforming the antioxidants which could ameliorate the renal I-R injury in mice. Malondialdehyde (MDA) of rat serum was determined using MDA colorimetric assay kit (E-BC-K025-M).
Dilution of sample
It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the formal experiment and the detection range (2.92-40 μmol/L).
