补体因子 I,又称 C3b/C4b 灭活剂,由 CFI 基因编码的蛋白质。通过裂解细胞结合或液相 C3b 和 C4b 来调节补体的激活。它是一种可溶性糖蛋白,在人体血液中循环的平均浓度为 35 微克/毫升。因子 I 主要在肝脏中合成,也在单核细胞、成纤维细胞、角质细胞和内皮细胞中合成。合成后,它是一条66kDa 的多肽链,在 6 个位置有 N-连接的糖。然后,因子 I 被呋喃酶裂解, 产生成熟的因子 I 蛋白,它是重链(残基 19-335,51kDalton)和轻链(残基 340-583,37kDalton)的二硫键连接的二聚体。只有成熟蛋白才有活性。 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因子I(CFI)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因子I(CFI)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 CFI. 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 CFI 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.
