  • Griess test - Wikipedia
    The Griess test is an analytical chemistry test which detects the presence of nitrite ion in solution One of its most important uses is the determination of nitrite in drinking water
  • Nitrate and Nitrite Reduction Test Protocols - American Society for . . .
    In 1879, Griess developed a reagent for the detection of nitrite in solutions The reagent, an acid solution of sulfanilic acid and alpha-naphthylamine, undergoes a diazotization reaction with nitrites, forming a red azo dye (17)
  • 碧云天生物技术-一氧化氮检测试剂盒(S0021S) - Beyotime
    碧云天生产的一氧化氮检测试剂盒采用了经典的Griess Reagent，并对其测定的溶液体系进行了优化，使检测下限达到1μM，在1-100μM范围内有非常完美的线性关系。
  • GRIESS ASSAY FOR NITRITE DETERMINATION - Bowdish
    • Nitrate can be reduced to nitrite using nitrate reductase prior to the Griess assay • The reaction only occurs when the pH of the mixture (Griess reagent mixture and sample) dropped below 2
  • Griess Test - an overview | ScienceDirect Topics
    Testing of urine for nitrite is important because it can be used to detect urinary tract infection The basis of the spot test used in the Nitur-Test ® (Boehringer Mannheim) and in the Rapignost ® strip system (Hoechst AG) is the classical Griess test
  • High-Throughput Griess Assay of Nitrite and Nitrate in Plasma and Red . . .
    Although several techniques can be used to measure nitrite, the most frequently employed is the century-old Griess reaction, which is a staple of most dye chemistry
  • Griess reagent (ab234044) - Abcam
    Nitrite is reduced to nitrogen oxide using Griess Reagent I Nitrogen oxide then reacts with Griess Reagent II forming a stable product that can be detected by its absorbance at 540 nm The two-step assay is simple, fast and can detect nitrite levels as low as 1 nmol well
  • Griess Reagent System Technical Bulletin TB229 - Promega Corporation
    The Griess Reagent System is based on the chemical reaction shown in Figure 1, which uses sulfanilamide and N-1- napthylethylenediamine dihydrochloride (NED) under acidic (phosphoric acid) conditions
  • Nitrite Reduction Test – Principle, Procedure, Result
    Griess developed a reagent for detecting nitrite in solutions in 1879 A solution of sulfanilic acid and alphanaphthylamine undergoes a diazotization reaction with nitrites, resulting in the formation of a red azo dye
  • Griess Reagent System - Promega
    The Griess Reagent System measures nitrite (NO 2–), one of two primary stable and nonvolatile breakdown products of nitric oxide (NO) Nitric oxide is an important physiological messenger and effector molecule in many biological systems, including immunological, neuronal and cardiovascular tissues
