Product Summary for Mouse IL-2 Quantikine ELISA Kit
The Quantikine Mouse IL-2 Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse IL-2 levels in cell culture supernates and serum. It contains E. coli-expressed recombinant mouse IL-2 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse IL-2 accurately. Results obtained using natural mouse IL-2 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 mouse IL-2.

Recovery for Mouse IL-2 Quantikine ELISA Kit
The recovery of mouse IL-2 spiked to three levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (n=6) | 102 | 84-110 |
| Serum (n=6) | 102 | 96-108 |
Linearity
To assess the linearity of the assay, five or more samples containing and/or spiked with various concentrations of mouse IL-2 in each matrix were diluted with Calibrator Diluent and then assayed.
