低氧诱导因子-1α,又称HIF-1-α,是由HIF1A基因编码的异源二聚体转录因子低氧诱导因子1(HIF-1)的一个亚单位。HIF1A是一个含有基本螺旋环螺旋PAS结构域的蛋白质,被认为是细胞和发育对缺氧反应的主转录调节器。HIF1是一个异源二聚体的基本螺旋环螺旋结构,由HIF1A、α亚单位(本蛋白)和芳烃受体核转译器(Arnt)、β亚单位组成。HIF1A在C端附近含有一个基本螺旋环螺旋结构域,之后是两个不同的PAS(PER-ARNT-SIM)结构域,以及一个PAC(PAS相关C端)结构域。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人低氧诱导因子-1α(HIF-1α)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低氧诱导因子-1α(HIF-1α)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 HIF-1α. 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 HIF-1α 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.
