C4b结合蛋白(C4BP)是一种参与补体系统的蛋白质复合物,它在补体系统中发挥着抑制作用。C4BP有一个章鱼状的结构,有一个中心柄和七个分支的α-链。人类血液中的C4BP的主要形式是由7个相同的α链和一个独特的β链组成,而β链又与抗凝血剂、维生素K依赖的蛋白S结合。它也是一种大的糖蛋白(500 kDa),估计血浆浓度为200微克/毫升,主要在肝脏合成。编码C4BPα链(C4BPA)和β链(C4BPB)的基因位于1号染色体长臂上的补体激活调节器(RCA)基因组中,与其他补体抑制剂相邻。 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C4b结合蛋白α链(C4BPa)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C4b结合蛋白α链(C4BPa)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 C4BPa. 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 C4BPa 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.
