Recovery for cGMP Parameter Assay Kit
The recovery of cGMP spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 100 | 91-108 |
| Cell Lysates (n=1) | 92 | 80-98 |
| EDTA Plasma (n=4) | 91 | 74-105 |
| Saliva (n=4) | 102 | 80-123 |
| Urine (n=4) | 90 | 77-98 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of cGMP were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
