一般描述

Griess 试剂用于亚硝酸盐离子的定量分析。亚硝酸根离子与硝酸根离子通过重氮偶联反应形成粉红色的重氮染料。亚硝酸盐(或硝酸盐)离子的浓度与所得红色溶液的颜色强度成正比。

  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.

It has been proposed that the induction of cellular immunity and resistance to intracellular pathogens is dependent upon CD40 ligand (CD40L). In the present study we show that this proposal is not ubiquitously supported. Mice genetically deficient in CD40L (CD40LKO)
