1. Can the griess reagent solution be stored for longer if I keep it in the freezer? 2. Does my sample (a supernatant of cell culture media) has to be centrifuged first before I do the assay? 3. Do I add the reagent to my standard (NaNO2) as well?

if we dissolve Griess reagent 40 mg/ml in water then what will be its concentration (molarity).
1 answer-
This product is a multi-component reagent, thus a molarity is not available. When prepared according to instructions, the prepared solution will contain 0.288% (w/v) of sulfanilamide and 0.016% (w/v) naphthylethylene diaminedihydrochloride. In addition, the product also includes an unreported amount of phosphoric acid.

Is there an enzymatic method to convert nitrate to nitrite?
1 answer-
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).
