Product Summary for Mouse/Rat IL-22 Quantikine ELISA Kit
The Quantikine Mouse/Rat IL-22 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse and rat IL-22 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mouse IL-22 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse or rat IL-22 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 naturally occurring mouse and rat IL-22.

Recovery for Mouse/Rat IL-22 Quantikine ELISA Kit
The recovery of IL-22 spiked to three levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Mouse Cell Culture Supernates (n=4) | 98 | 93-103 |
| Mouse EDTA Plasma (n=4) | 95 | 86-106 |
| Mouse Heparin Plasma (n=4) | 94 | 83-102 |
| Mouse Serum (n=4) | 91 | 84-99 |
| Rat Cell Culture Supernates (n=4) | 98 | 91-102 |
| Rat EDTA Plasma (n=4) | 97 | 91-111 |
| Rat Heparin Plasma (n=4) | 93 | 88-101 |
| Rat Serum (n=4) | 96 | 90-107 |
Linearity
To assess the linearity of the assay, samples spiked with high concentrations of IL-22 in each matrix were diluted with the appropriate Calibrator Diluent and assayed.
