Product Summary
The Parameter Total Nitric Oxide kit has two assay options. Endogenous nitrite is measured in the first option. In the second option, nitrate is converted to nitrite using nitrate reductase and total nitrite is measured. To obtain the nitrate concentration, endogenous nitrite is subtracted from the total nitrite value.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Recovery
The recovery of the nitrate standard spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (Nitrite Assay) (n=10) | 107 | 91-115 |
| Plasma (Nitrate Assay) (n=25) | 98 | 87-110 |
| Plasma (Nitrite Assay) (n=20) | 104 | 92-117 |
| Serum (Nitrate Assay) (n=10) | 95 | 89-101 |
| Serum (Nitrite Assay) (n=10) | 109 | 98-118 |
| Urine (Nitrite Assay) (n=10) | 101 | 87-112 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of the nitrate standard were serially diluted with the Reaction Diluent to produce samples with values within the dynamic range of the assay.
