Description
Malondialdehyde (MDA) is one of the end products of lipid peroxides, the MDA concentration in cell or tissue samples can indicate lipid peroxidation which is important in the fields of oxidative stress and ferroptosis. MDA is also called reactive aldehyde and reacts with amino and thiol groups to cause protein denaturation and DNA damage, so it is also measured in various disease studies such as cancer and diabetes.
Dojindo's MDA Assay Kit uses the TBARS method to detect MDA by measuring the fluorescence or absorbance of the adduct of MDA and thiobarbituric acid that develops color according to the amount of MDA.
Manual
Technical info
The fluorometric method can measure both cell samples and tissue samples, the colorimetric method can only measure tissue samples. Please choose the proper method according to the expected concentration of samples.
Fluorometric | Colorimetric | Amount of Sample | Detection range | |
---|---|---|---|---|
Cell | OK | × | 1-3×107 cells | 1-10 µmol/l |
Tissue | OK | OK |
Fluorometric: 10-30 mg Colorimetric: 20-50 mg |
Fluorometric: 1-10 µmol/l Colorimetric: 1-50 µmol/l |
Simple Procedures
Other company's TBA method MDA assay kit requires a substrate weighing procedure. however, Dojindo's Kit doesn't need a weighing procedure, thus greatly reducing the measuring time and the variation of assay results due to weighing errors.
Applicaiton Data: MDA level in Ferroptosis induced Cells
Using Dojindo's MDA Assay Kit measuring the changes of MDA level in erastin (an inhibitor of xCT, Cystine/Glutamate transporter) treated HepG2 cells, the result shows that the GSSH/GSH ratio is decreased and the MDA, intracellular Fe2+, ROS, Lipid peroxide level is increased.

Q & A
-
Q
What is the principle of this kit?
-
A
This kit uses 2-thiobarbituric acid(TBS) as a substrate. By measuring the absorbance or fluorescence intensity of the TBA adduct formed by the reaction of MDA and TBA, and comparing with the standard curve, the MDA concentration in the sample can be simply measured.
-
Q
How many samples can be tested by this kit?
-
A
When testing the sample in triplicates, 24 samples can be tested by this kit.
-
Q
What is the storage condition of the prepared solution?
-
A
Substrate stock solution is stable for 2 months under -20℃.
Antioxidant PBS solution and Working solution is stable for 24 hours.
-
Q
Do I need to normalize the result by cell numbers?
-
A
If there is no change in cell number after drug stimulation, the normalization by cell number is not necessary.
If the number of cells changes, the normalized result by protein quantification is more accurate, in such case, the BCA method is recommended for protein quantification.
