Griess Reagent Kit for Measuring Nitrite Ions

Nitric oxide (NO) plays diverse roles in processes such as vasodilation, neurotransmission, immune responses, and controlling cell proliferation. It is also associated with numerous diseases, including cardiovascular disease, neurodegenerative disorders, and cancer.¹⁾
Griess Reagent Kit (1) is a colorimetric reagent kit for the quantification of nitrite ions (NO₂⁻), a stable metabolite of NO. NO₂⁻ in the sample reacts with sulfanilamide of 1 to form a diazonium salt. This salt then reacts with N-(1-naphthyl)ethylenediamine (NED) in 1 to produce the reddish-purple diazo dye, which has a maximum absorption peak near 540 nm. By measuring this color intensity, the NO₂⁻ concentration can be quantified, and consequently, the NO concentration can be determined indirectly.^2,3)
