Nitrite Assay Kits

Nitrite assay kits are versatile laboratory tools to determine the abundance or concentration of nitrite in biological samples. Nitrite (NO2) is an anion that is part of the nitrogen cycle and is a key intermediate in the nitrification and denitrification processes. Nitrite assays generally utilize nitrite-reactive compounds that can be measured colorimetrically or fluorometrically. One example is the Griess reaction, in which two subsequent reactions with nitrite form a deep purple azo compound. Fluorometric nitrite assays involve the reaction with a fluorescent probe (such as DAN). Nitrite assays are used in a variety of applications, including studying the effects of NO or NO2 in physiological and pathological processes, including nitrogen metabolism, oxidative stress, inflammation cardiovascular health, and the central nervous system, as well as in microbial or environmental investigations around the nitrogen cycle. When choosing an assay kit, consider important specifications such as the assay detection range, recommended sample types, and the components included within the kit.
