摘要：

Superoxide plays a key role in normal immune function and inflammatory diseases. In order to evaluate normal immune function or screen inhibitors of superoxide production for treating inflammatory diseases, it is very important to detect superoxide with good accuracy, sensitivity, and flexibility. In present study, we investigated three analysis methods of superoxide, colorimetric assay by WST-8, fluorescence assay by dihydroethidium and chemiluminescence assay by lucigenin, compared their precisions, specificities, sensitivities and time curve characteristics in superoxide analysis, and then validate their values in the screening of anti-inflammatory compounds. The results reveal that three analysis methods of superoxide all have good precisions and high specificities but have different sensitivities and time curve characteristics, which suggest their different applications. In addition, they can all be used in the screening of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase inhibitors and anti-inflammatory compounds.
