  • 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 The Griess diazotization reaction, on which the Griess reagent relies, was first described in 1858 by Peter Griess
  • Nitrate and Nitrite Reduction Test Protocols
    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)
    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。 检测速度极快，完成一条标准曲线或5-10个样品的测定只需3分钟。
  • GRIESS ASSAY FOR NITRITE DETERMINATION - Bowdish
    Convert absorbance reading to nitrite concentration based on calibration curve 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 This can be achieved with the addition of 1 0 M H2SO4
  • Griess Test - an overview | ScienceDirect Topics
    The Griess test similarly involves a reagent (α-naphthylamine, and sulfanilic acid in acetic acid) targeting nitrites This test is based on the formation of a diazonium salt when nitrite in acid solution reacts with a primary aromatic amine
  • Griess reagent (ab234044) - Abcam
    Griess Reagent Kit ab234044 uses a classic protocol for the estimation of nitrite in biological samples 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
  • High-Throughput Griess Assay of Nitrite and Nitrate in Plasma . . .
    An optimized spectrophotometric Griess method for nitrite–nitrate affords sensitivity in the low millimolar range and precision within ±2 μM for both nitrite and nitrate, requiring 100 μL of scarcely available plasma sample or less than 50 μL of red blood cells
