Product Summary for Mouse IL-12 p40 Allele-specific Quantikine ELISA Kt
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 and mouse serum. It contains recombinant mouse IL-12 p40 homodimer and antibodies raised against the recombinant factor. 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.

Background: IL-12/IL-23 p40
IL-12 (Interleukin-12) is a secreted heterodimeric cytokine that contains disulfide-linked p35 and p40 subunits. The p40 subunit is also a subunit of the heterodimeric IL-23. IL-12 is produced by macrophages, dendritic cells, monocytes, Langerhans cells, neutrophils, keratinocytes, microglia, and non-germinal center B cells. It acts through a receptor complex that contains the ligand binding IL-12 R alpha 1 and the signal transducing IL-12 R alpha 2. IL-12 can enhance cytotoxic activity and induce Interferon-gamma production in NK cells, T cells and dendritic epidermal T cells. In conjunction with IL-23 and IL-27, IL-12 promotes the development of a Th1 immune response.
