血管紧张素是一种肽类激素，可引起血管收缩和血压升高。它是肾素-血管紧张素系统的一部分，该系统调节血压。血管紧张素还刺激肾上腺皮质释放醛固酮以促进肾脏保留钠。血管紧张素1-9被ACE2从血管紧张素-1裂解，并可被ACE进一步加工，产生血管紧张素1-7、血管紧张素1-5和血管紧张素1-4。 本试剂盒采用竞争法酶联免疫吸附试验（ELISA）。往预先包被有人血管紧张素1-9(Ang1-9)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血管紧张素1-9(Ang1-9)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 Ang1-9 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 Ang1-9 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.
