Glutamic Acid and NAD+ produce α-ketoglutaric acid, NADH and NH4+ under the action of glutamic acid dehydrogenase. The maximum absorption of NADH is at 340 nm. The content of glutamic acid can be calculated by measuring the change of NADH.
Applications
Used to detect glutamic acid content in serum, plasma, animal tissue, cells and cell supernatant.
Procedure
1. Prepare standard samples and experimental samples. 2. Add reaction reagents in order for reaction. 3. Measure the absorbance of each tube. 4. Make the mark curve and calculate the result.
