Product Summary for Canine IFN-gamma Quantikine ELISA Kit
The Quantikine Canine IFN-gamma Immunoassay is a 4 hour solid-phase ELISA designed to measure canine IFN-gamma in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant canine IFN-gamma and antibodies raised against the recombinant factor. Results obtained for naturally occurring canine IFN-gamma showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural canine IFN-gamma.

Recovery for Canine IFN-gamma Quantikine ELISA Kit
The recovery of canine IFN-gamma spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (n=4) | 103 | 92-111 |
| EDTA Plasma (n=4) | 96 | 86-102 |
| Heparin Plasma (n=4) | 98 | 93-106 |
| Serum (n=4) | 96 | 83-107 |
Linearity
To assess the linearity of the assay, samples containing or spiked with high concentrations of canine IFN-gamma in each matrix were diluted with Calibrator Diluent and assayed.
