Product Summary for Rat IFN-gamma Quantikine ELISA Kit
The Quantikine Rat IFN-gamma Immunoassay is a 4.5 hour solid phase ELISA designed to measure rat IFN-gamma levels in cell culture supernates and serum. It contains E. coli-expressed recombinant rat IFN-gamma and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate recombinant rat IFN-gamma accurately. Results obtained using natural rat IFN-gamma showed dose curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural rat IFN-gamma.

Recovery for Rat IFN-gamma Quantikine ELISA Kit
The recovery of rat IFN-gamma spiked to three levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (n=6) | 108 | 89-119 |
| Serum (n=6) | 100 | 89-111 |
Linearity
To assess the linearity of the assay, five or more samples containing and/or spiked with various concentrations of rat IFN-gamma in each matrix were diluted with Calibrator Diluent and then assayed.
