Product Summary for Mouse IL-12 p40 NonAllele-specific Quantikine ELISA
The Quantikine Mouse IL-12/IL-23 p40 Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse p40 subunit in IL-12 p70, IL-23, p40 homodimer, and p40 monomer in cell culture supernates, mouse serum, and plasma. It contains recombinant mouse IL-12/23 p40 homodimer and antibodies raised against the p40 subunit of recombinant mouse IL-12 p70. This immunoassay has been shown to accurately quantitate the recombinant mouse IL-12/IL-23 p40. Results obtained using natural mouse IL-12/IL-23 p40 showed dose-response 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-12/IL-23 p40.

Recovery for Mouse IL-12 p40 NonAllele-specific Quantikine ELISA
The recovery of mouse IL-12/IL-23 p40 spiked to three levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Supernates (n=4) | 104 | 98-108 |
| EDTA Plasma (n=4) | 99 | 81-112 |

Background: IL-12/IL-23 p40
Interleukin 12 (IL-12), also known as natural killer cell stimulatory factor (NKSF) or cytotoxic lymphocyte maturation factor (CLMF), is a heterodimeric pleiotropic cytokine made up of a 40 kDa (p40) subunit and a 35 kDa (p35) subunit. The IL-12 p40 subunit is shared by IL-23, another heterodimeric cytokine that has biological activities similar to, as well as distinct from, IL-12. IL-12 is produced by macrophages and B cells and has been shown to have multiple effects on T cells and natural killer (NK) cells. While mouse IL-12 is active on both human and mouse cells, human IL-12 is not active on mouse cells.
