C-反应蛋白(CRP)是一种在血浆中发现的环状(环形)五聚体蛋白,其循环浓度随着炎症的发生而上升。它是一种源自肝脏的急性期蛋白,在巨噬细胞和T细胞分泌白细胞介素-6后增加。它的生理作用是与表达在死亡或濒死细胞(和一些类型的细菌)表面的溶血磷脂酰胆碱结合,以便通过C1q激活补体系统。CRP由肝脏合成,对巨噬细胞和脂肪细胞释放的因子作出反应,它是五联蛋白家族的一员。它与C肽(胰岛素)或C蛋白(血液凝固)没有关系。C-反应蛋白是第一个被确认的模式识别受体(PRR)。 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C反应蛋白(CRP)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C反应蛋白(CRP)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 CRP. 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 CRP 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.
