General description
The Griess reagent is used for the quantitative analysis of nitrite ions. Present nitrite (as well as nitrate) ions will form a pink diazo dye by diazonium coupling reaction with N-(1-Naphthyl)ethylenediamine. The concentration of nitrite (or nitrate) ions is proportional to the color intensity of the resulting red solution.

Using two-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis, we found that copper/zinc superoxide dismutase (Cu/Zn-SOD, SOD-1) was induced in constructed CCR5 stably transfected HEK 293 cells, but not in mock cells, treated with CCL5. CCL5-induced SOD-1 expression was also confirmed in
