纤溶酶原启动物抑制因子 1(PAI-1)也被称为内皮凝血酶原激活剂抑制剂或血清蛋白 E1,由 SERPINE1 基因编码的蛋白质。PAI-1 升高是血栓形成和动脉粥样硬化的一个风险因素。PAI-1 是一种丝氨酸蛋白酶抑制剂(serpin), 其功能是作为组织纤溶酶原激活剂(tPA)和尿激酶(uPA)的主要抑制剂, 后者是纤溶酶原的激活剂,因此是纤维蛋白溶解(血凝块的生理性分解)。它是一种丝氨酸蛋白酶抑制剂(serpin)蛋白(SERPINE1)。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人1型组织纤溶酶原激活物抑制剂(tPAI-1)捕获抗体的微孔中,依次加入样本、标准品、生物素标记的检测抗体,HRP酶结合物,中间经过温育和洗涤,用底物TMB显色,TMB在过氧化物酶(HRP)的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。颜色的深浅和样本中的人1型组织纤溶酶原激活物抑制剂(tPAI-1)呈正相关。用酶标仪在450nm 波长下测定吸光度(OD值),计算样本浓度。
This kit employs the sandwich enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with a capture antibody specific to Human tPAI-1. Following this, the sample, standards, a biotin-conjugated detection antibody, and an HRP (horseradish peroxidase)-labeled conjugate are added sequentially to the wells. The procedure involves incubation and wash steps between each addition. For detection, TMB substrate is used. TMB yields a blue color in the presence of the peroxidase activity of HRP. The reaction is then stopped with an acid solution, which converts the blue color to a final yellow color. The intensity of the yellow color is directly proportional to the concentration of Human tPAI-1 present in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader. Finally, the concentration of the target analyte in the sample is calculated based on the standard curve generated from the standards.
