CheKine™ Nitric Oxide (NO) Assay Kit

Product Information

  • Product name

    CheKine™ Nitric Oxide (NO) Assay Kit

  • Application notes

    CheKine™ Nitric Oxide Assay Kit is designed to accurately measure NO production following reduction of nitrate to nitrite by using improved Griess method. The Griess assay’s mechanism is summarized as the azo coupling between diazonium species, which are produced from sulfanilamide with NO2- and naphthylethyl -enediamine, resulting in a colorimetric (540 nm) product proportional to the NO metabolite present.

Product Properties

  • Kit components

    • NaNO2 Standard (1M)
    • Griess Reagent I
    • Griess Reagent II
    • VCl3 reagent
    • ZnSO4

  • Features & Benefits

    • Determination of Nitric oxide in serum, plasma, cell/tissue samples, urine and other biological fluids.
    • Detect biological samples at a level of 1-100 µM.
    • Rapid and reliable, Using an optimized VCl3 reagent, the time required for reduction of NO3 - to NO2 - is short.
    • Simple and high-throughput, the procedure involves mixing sample with three reagents, incubation and reading the optical density. Can be readily automated to measure thousands of samples per day.

  • Usage notes

    • It is recommended to perform several dilutions of your sample to ensure the readings are within the standard value range.
    • Fresh samples are necessary for good results. If not assayed immediately, samples can be stored at -80°C for one month.

  • Storage instructions

    Storage at -20°C and Keep from light immediately upon receipt. Kit has a storage time of 12 months from receipt. Refer to list of materials supplied for storage conditions of individual components.
