低氧诱导因子1(HIF1)是由HIF-1α和HIF-1β亚基组成的异构体,存在于所有的后生动物物种。HIF-1调节缺氧诱导基因,如红细胞生成素(EPO)、血管内皮生长因子(VEGF)和诱导性一氧化氮合成酶。这些基因的缺氧反应元件(HRE)包含一个HIF-1结合位点,以及其他DNA序列。HIF-1 属于转录因子碱性螺旋-环-螺旋 (bHLH) 家族的 PER-ARNT-SIM (PAS) 亚家族。α 和 beta 亚基结构相似,都包含以下结构域:N 端 – 用于 DNA 结合的 bHLH 结构域,中心区域 – Per-ARNT-Sim (PAS) 结构域,促进异二聚化,C 端 – 募集转录共调节蛋白 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1(HIF1)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1(HIF1)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 HIF1. 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 HIF1 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.
