About This Kit
The Human Interleukin-12/Interleukin-23 p40 subunit (Hu IL-12/IL-23 p40) ELISA quantitates Hu IL-12/IL-23 p40 in human serum, plasma, buffered solution, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu IL-12/IL-23 p40.
Principle of the method
The Human IL-12/IL-23 p40 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The 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.
Rigorous validation
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.
Target information
IL-12 is an interleukin produced by dendritic cells, neutrophils, macrophages and human lymphoblastoid cells as a result of antigenic stimulation. IL-12 is a heterodimeric cytokine encoded by IL-12A (p35) and IL-12B (p40). IL-23 is a heterodimeric cytokine that shares a subunit with IL-12 (IL-12B) along with an IL-23A (IL-23p19) subunit. Functionally, IL-12 increases the expression of vascular endothelial adhesion molecule-1 on the endothelium, directs leukocytes towards tumors and facilitates the ischemic-hemorrhagic necrosis of the tumor tissue. In comparison, IL-23 plays an important role in stimulating memory T-cells, and is required for the induction, expansion, maintenance and downstream effector functions of Th17 cells, which play a vital role in upregulating neutrophil chemokines and various pro-inflammatory cytokines.
