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. Range: 11.70 - 750 pg/mL. Sensitivity: 2.7 pg/mL. Time: 4.5 hours
