| 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ELA2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ELA2会与酶标板上的包被抗体充分结合；洗板后加入生物素化抗人ELA2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ELA2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ELA2，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ELA2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ELA2的浓度。 |
| Background | Neutrophil Elastase (ELA2)，also known as polymorphonuclear leukocyte elastase，is a serine protease belonging to the chymotrypsin family. Located primarily in the azurophil granules of polymorphonuclear leukocytes，ELA2 function results in the degradation of many extracellular matrix macromolecules. Alpha-1 Antitrypsin (Serpin A1) and secretory leukocyte protease inhibitor (SLPI) have been shown to inhibit ELA2 activity. ELA2 may be involved in lung emphysema，cystic fibrosis，the adult respiratory distress syndrome (ARDS)，rheumatoid arthritis，tumor invasion and infectious diseases |
