生长分化因子2(GDF-2;BMP-9)是由GDF2基因编码的蛋白质。它包含一个N端TGF-beta样原肽（原域）（残基56-257）和一个C端转化生长因子β超家族结构域（325-428）。它以原复合物的形式分泌，由BMP9生长因子二聚体非共价地与两个BMP9原域分子结合，呈开臂构象。它是肝细胞中血色素（一种具有抗菌特性的阳离子肽）的有效诱导剂，可以调节铁的代谢。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人生长分化因子2(GDF-2;BMP-9)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生长分化因子2(GDF-2;BMP-9)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 GDF-2;BMP-9. 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 GDF-2;BMP-9 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.
