纤维蛋白原α是一种蛋白质,是由FGA基因编码的。该基因编码的蛋白是纤维蛋白原的α成分,纤维蛋白原是一种血液中的糖蛋白,由三对不相同的多肽链组成。血管损伤后,纤维蛋白原被凝血酶裂解形成纤维蛋白,它是血凝块中最丰富的成分。此外,纤维蛋白原和纤维蛋白的各种裂解产物调节细胞的粘附和扩散,显示出血管收缩和趋化活性,并且是几种细胞类型的有丝分裂剂。该基因的突变导致了一些疾病,包括纤维蛋白原异常、纤维蛋白原低下、纤维蛋白原异常和肾脏淀粉样变性。替代性剪接导致两种异构体,它们的羧基端部有所不同。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有人纤维蛋白原α(FGα)抗原的微孔中,依次加入样本、标准品、Biotin标记的抗体,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纤维蛋白原α(FGα)呈负相关。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 competitive enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Human FGα antigen. The sample, standards, a biotin-labeled antibody, and an HRP enzyme conjugate are then added sequentially to the wells. The procedure includes incubation and wash steps between each addition. TMB substrate is used for color development. In the presence of the peroxidase (HRP) enzyme, TMB is catalyzed to produce a blue color, which is then converted into a final stable yellow color upon the addition of an acid stop solution. The intensity of the resulting yellow color is inversely proportional to the concentration of Human FGα in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader, and the concentration of the target analyte in the sample is calculated based on the standard curve.
