补体成分 C9(C9)是一种参与补体系统的 MACPF 蛋白,是先天免疫系统 的一部分。一旦被激活,大约 12-18 个 C9 分子聚合在目标细胞膜上形成孔 隙,导致裂解和细胞死亡。C9 是补体膜攻击复合物(MAC)的一个成员, 它还包括补体成分 C5b、C6、C7 和 C8。MAC 的形成通过三种不同的途径: 经典途径、替代途径和凝集素途径。C9 形成的孔隙是感染期间杀死细菌细胞 的重要途径,目标细胞往往被多个 MAC 覆盖。缺少 C9 的临床影响是感染革 兰氏阴性细菌脑膜炎。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人补体成分C9(C9)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补体成分C9(C9)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 C9. 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 C9 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.
