Abstract:
It has been well-established that malondialdehyde (MDA), which is generated during the process of lipid peroxidation, is a commonly known biomarker for oxidative stress. Therefore, the serum levels of MDA are detected by using the lipid peroxidation assay with commercially available kit to determine the induction of oxidative stress in rat models.
Insights
Malondialdehyde (MDA) indicates oxidative stress. Detecting MDA levels in rat serum using a lipid peroxidation assay helps determine oxidative stress induction.
