Mouse IL-13 ELISA Kit

Due to the possibility of mismatching between antigens from other origin and antibodies used in our kits (e.g., antibody targets conformational epitope rather than linear epitope), some native or recombinant proteins from other manufacturers may not be recognized by our products.

Principle of the Assay

This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for IL-13 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IL-13 present is bound by the immobilized antibody. Following incubation unbound samples are removed during a wash step, and then a detection antibody specific for IL-13 is added to the wells and binds to the combination of capture antibody-IL-13 in sample. Following a wash to remove any unbound combination, and enzyme conjugate is added to the wells. Following incubation and wash steps a substrate is added. A coloured product is formed in proportion to the amount of IL-13 present in the sample. The reaction is terminated by addition of acid and absorbance is measured at 450nm. A standard curve is prepared from seven IL-13 standard dilutions and IL-13 sample concentration determined.

Target Information

IL-13 (Interleukin-13) plays a key role in the pathogenesis of allergy, cancer, and tissue fibrosis. It is secreted by several helper T cell subsets, NK cells, mast cells, eosinophils, basophils, and visceral smooth muscle cells. IL-13 suppresses the production of proinflammatory cytokines and other cytotoxic substances by macrophages, fibroblasts, and endothelial cells. It promotes B cell activation, immunoglobulin class switching to IgE, and the upregulation of CD23/Fc epsilon RII. IL-13 signals through a receptor complex containing IL-13 R alpha 1 and IL-4 R alpha. This complex also functions as the type 2 IL-4 receptor. IL-13 R alpha 2 binds IL-13 and prevents IL-13 from signaling through the IL-13 R alpha 1/IL-4 R alpha complex. IL-13-bound IL-13 R alpha 2 can directly promote tumor cell invasiveness and the development of tissue fibrosis.
