IL-12 High Sensitivity ELISA Kit (Human)

This gene encodes a subunit of a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. The cytokine is a disulfide-linked heterodimer composed of the 35-kD subunit encoded by this gene, and a 40-kD subunit that is a member of the cytokine receptor family. This cytokine is required for the T-cell-independent induction of interferon (IFN) -gamma, and is important for the differentiation of both Th1 and Th2 cells. The responses of lymphocytes to this cytokine are mediated by the activator of transcription protein STAT4. Nitric oxide synthase 2A (NOS2A/NOS2) is found to be required for the signaling process of this cytokine in innate immunity.

Aviva Systems Biology IL-12p70 High Sensitivity ELISA Kit (Human) (OKDB00043) is designed for the highly sensitive in-vitro quantitative measurement of recombinant or natural IL-12p70 in human serum, plasma buffered solutions or cell culture medium. The kit is based on standard sandwich enzyme-linked immuno-sorbent assay methods along with an additional detection process employing a polymerization step to amplify the number of detector bound HRP molecules. A monoclonal antibody specific for IL-12p70 has been pre-coated into wells of a 96-well plate. Standards or test samples are added to the wells and incubated. After washing, a biotinylated detector antibody specific for IL-12p70 is added, incubated and followed by washing. Streptavidin-HRP conjugate is then added, incubated and unbound conjugate is washed away. Amplification is achieved by adding a Biotin-Tyramine reagent, incubating and washing, followed by a second incubation with Streptavidin-HRP conjugate. An enzymatic reaction is then produced through the addition of TMB substrate which is catalyzed by HRP to generating a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm and is quantitatively proportional to the amount of sample IL-12p70 captured in well.
