Abcam’s IL-12 Human in vitro ELISA Set is designed for the quantitative measurement of IL-12 in cell culture supernatants, buffered solutions, serum, plasma and other body fluids.
The IL12p70 ELISA Set includes both the capture and the detection antibodies as well as Horse-Radish peroxidase conjugated Streptavidin (HRP-Strep) and TMB which are the reagents used in the colour development step.
This ELISA Set is intended to measure human IL12p70 in cell -culture supernatants, as well as in serum and plasma samples. The enclosed procedures provide general guidelines for ELISA preparation. This procedure may need some optimization depending on the plastic, matrix, standard range.
Interleukin 12 is a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. Interleukin 12 is a disulfide-linked heterodimer composed of the 35 kD cytokine receptor like subunit encoded by IL12A gene, and a 40 kD subunit encoded by IL12B.
This cytokine is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. It is required for the T-cell-independent induction of interferon (IFN)-gamma, and is important for the differentiation of both Th1 and Th2 cells.
This cytokine has been found to be important for sustaining a sufficient number of memory/effector Th1 cells to mediate long-term protection to an intracellular pathogen. 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.
Overexpression of this gene was observed in the central nervous system of patients with multiple sclerosis (MS), suggesting a role of this cytokine in the pathogenesis of the disease.
The promoter polymorphism of this gene has been reported to be associated with the severity of atopic and non-atopic asthma in children.
