| 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。将抗人ET-1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，标准品和样本中的人ET-1会与酶标板上的包被抗体充分结合；加入生物素化抗人ET-1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人ET-1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人ET-1，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），样本中的人ET-1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人ET-1的浓度。 |
| Background | Endothelin-1 (ET-1) is produced by many tissues including lung，kidney，brain，endocrine glands，and placenta. It is also expressed by several cell types including，mast cells，endothelial cells，epithelial and smooth muscle cells. The most prominent source is vascular endothelium. ET-1 is best known as a potent vasoconstrictor. Elevated blood ET-1 levels are associated with a variety of diseases，possibly as a function of a stress response. |
