Product Information
KE20038 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The rat IL-4 ELISA kit is to be used to detect and quantify protein levels of endogenous rat IL-4. The assay recognizes rat IL-4. An antibody specific for rat IL-4 has been pre-coated onto the microwells. The rat IL-4 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for rat IL-4 is added to detect the captured rat IL-4 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 450 nm with the correction wavelength set at 630 nm.

Background Information
Interleukin-4 (IL-4), a member of the α-helical cytokine family, is produced by activated CD4 + T cells, basophils, and mast cells. It promotes the proliferation and differentiation of antigen presenting cells. IL-4 also plays a pivotal role in antibody isotype switching and stimulates the production of IgE. This cytokine has been applied in the treatment of autoimmune disorder like multiple myeloma, cancer, psoriasis, and arthritis. IL-4 has also been extensively applied to inhibit detrimental effect of Th1. It may promote the growth of epithelial tumors by mediating increased proliferation and survival.
