| Detection Principle | Solarbio ELISA试剂盒采用基于双抗体夹心法的酶联免疫吸附检测技术。将抗大鼠IL-13单克隆抗体包被在酶标板上；分别加入梯度稀释的标准品和预稀释的样本，标准品和样本中的大鼠IL-13会与酶标板上的包被抗体充分结合；加入生物素化抗大鼠IL-13抗体，该抗体会与板子上包被抗体捕获的标准品和样本中的大鼠IL-13发生特异性结合；洗板后加入辣根过氧化物酶（HRP）标记的链霉亲和素，生物素与链霉亲和素会发生高强度的非共价结合；洗板后加入显色剂底物TMB，若反应孔中样品存在不同浓度的大鼠IL-13，则HRP会使无色TMB变成不同深浅（正相关）的蓝色物质，加入终止液后反应孔会变成黄色；最后，在λmax=450 nm（OD=450 nm）处测定反应孔样品吸光度（OD），样本中的大鼠IL-13浓度与OD成正比，通过绘制标准曲线和四参数拟合软件便可计算出样本中大鼠IL-13的浓度。 |
| 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 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. |
