The Bioaim Human IL-13 ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of IL-13 in Human serum, plasma and cell culture media. An antibody specific for Human IL-13 was coated on a 96-well plate. Standards and samples are added to the wells and any IL-13 present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human IL-13 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of IL-13 present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Inflammation;
Interleukin-13(IL-13) Background: IL-13 is cytokine secreted by many cell types, but especially T helper type 2 (Th2) cells, that is a mediator of allergic inflammation and disease. IL-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. IL-13 induces many features of allergic lung disease, including airway hyperresponsiveness, goblet cell metaplasia and mucus hypersecretion, which all contribute to airway obstruction.
