About This Kit
The Human Interleukin 12 p40 Antibody Pair Kit comes with pre-matched antibody pairs, standards, and streptavidin-HRP to develop your own enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of human IL-12 p40. Buffer reagents needed to complete the ELISA reaction are sold separate as a Buffer Kit for Antibody Pairs (Catalog No. CNB0011). The Assay Buffer included in this Buffer Kit can be used as a blocking reagent for ELISA plates as well as a diluent for ELISA standards and samples, detection antibody, and HRP conjugate.
Principle of the method
ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Target information
IL12B (IL-12 p40) encodes a subunit of interleukin 12, 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 40 kDa cytokine receptor like subunit encoded by this gene, and a 35 kDa subunit encoded by IL12A. This cytokine is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. 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. 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.
