General description

The Griess reagent is used for the quantitative analysis of nitrite ions. Present nitrite (as well as nitrate) ions will form a pink diazo dye by diazonium coupling reaction with N-(1-Naphthyl)ethylenediamine. The concentration of nitrite (or nitrate) ions is proportional to the color intensity of the resulting red solution.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. When using Product 03553, Griess’ reagent for nitrite, what product should I use to make a nitrite standard curve?

    Sodium nitrite (Product No. S2252 or 237213) can be used to make a standard curve. A typical standard curve would cover the range of 0-100 microMolar nitrite.

  4. Will phenol red interfere with the Griess reaction, Product 03553, Griess’ reagent for nitrite?

    No. Phenol red (which is a pH indicator present in some cell culture media) will not interfere with the Griess reaction.

  5. Is there an enzymatic method to convert nitrate to nitrite?

    A coupled assay to convert nitrate to nitrite has been published by Grisham, M.B., et al., Quantitation of nitrate and nitrite in extracellular fluids. Methods Enzymol., 268, 237-246 (1996).  For this protocol, we recommend using Product No. N7265 (Nitrate Reductase), Product No.L1378 (L-Lactic Dehydrogenase), Product No.N1630 (NADPH), Product No. P8574 (Sodium pyruvate) and Product No. F6625 (Flavin adenine dinucleotide disodium salt).

  6. What is the difference between Product G4410 Griess reagent (modified), and Product 03553, Griess reagent?

    There are many formulations of the Griess Reagent.  The formulations for these products are similar; both are proprietary.

  7. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.

Using two-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis, we found that copper/zinc superoxide dismutase (Cu/Zn-SOD, SOD-1) was induced in constructed CCR5 stably transfected HEK 293 cells, but not in mock cells, treated with CCL5. CCL5-induced SOD-1 expression was also confirmed in
