| Application: | Il17a, also named as Il-17, is a proinflammatory cytokine. Il-17, synthesized only by memory T cells and natural killer cells, has pleiotropic effects, mainly in the recruitment and activation of neutrophils. This cytokine regulates the activities of NF-kappaB and mitogen-activated protein kinases. This cytokine can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO). High levels of this cytokine are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis and multiple sclerosis. The Il-17 receptor is a type I transmembrane protein, that is widely expressed on epithelial cells, fibroblasts, B and T cells, and monocytic cells. In psoriatic skin lesions, both Th17 cells and their downstream effector molecules, e.g. Il-17 and IL-22, are highly increased. |
This test kit is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Mouse IL21 ELISA kit is to be used to detect and quantify protein levels of endogenous mouse IL21. The assay recognizes mouse IL21. An antibody specific for mouse IL21 has been pre-coated onto the microwells. The mouse IL21 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for mouse IL21 is added to detect the captured mouse IL21 protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450nm with the correction wavelength set at 630 nm.
