The Bioaim Porcine IL-13 ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of IL-13 in porcine serum, plasma and cell culture media. An antibody specific for porcine 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-porcine 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 (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 is known to induce changes in hematopoietic cells, but these effects are probably less important than that of IL-4. Furthermore, IL-13 can induce immunoglobulin E (IgE) secretion from activated human B cells. Interestingly, deletion of IL-13 from mice does not markedly affect either Th2 cell development or antigen-specific IgE responses induced by potent allergens. In comparison, deletion of IL-4 abrogates these responses. Thus, rather than a lymphoid cytokine, IL-13 acts more prominently as a molecular bridge linking allergic inflammatory cells to the non-immune cells in contact with them, thereby altering physiological function. IL-13 induces its effects through a multi-subunit receptor that includes the alpha chain of the IL-4 receptor (IL-4Rα) and at least one of two known IL-13-specific binding chains. Most of the biological effects of IL-13, like those of IL-4, are linked to a single transcription factor, signal transducer and activator of transcription 6 (STAT6). This can be resulted from an allergic reaction brought about when facing an Ala gene.
