Description
Detection principle
NO is easily oxidized to form NO2- in vivo or in aqueous solution, and a reddish azo compound is formed with the color developing agent, and the concentration of the azo compound is linearly related to the concentration of NO. The concentration of NO can be calculated indirectly by measuring the OD value at 550 nm.

Images
Ethanol administered significantly decreased the NO level in rat. Administering of lansoprazole (Lan), gallic acid (GA) in dose and Feiyangchangweiyan Capsule (FY) restored the NO level in stomachs. (#P<0.001 vs. Con group; *P<0.001 vs. Ethanol group)
D Zhou et al investigate mechanism of the gastroprotective effect of gallic acid against ethanol-induces gastric ulcer. Nitric oxide (NO) level in rat stomach was determined using NO colorimetric assay kit (E-BC-K035-S).
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 pre-experiment and the detection range (0.97-700 μmol/L).
The recommended dilution factor for different samples is as follows (for reference only):
|
Sample type |
Dilution factor |
