雌三醇(E3),被称为一种类固醇,是一种弱雌激素,也是一种次要的女性性激素。它是三种主要的内源性雌激素之一,其他是雌二醇和雌酮。 然而, 在怀孕期间,雌三醇由胎盘大量合成,是迄今为止体内产生最多的雌激素, 由于相对较高的代谢和排泄率,雌三醇的循环水平与其他雌激素相似。 相对于雌二醇,雌三醇和雌酮的雌激素活性都要弱得多。除了作为天然激素的作用外,雌三醇还被用作药物,例如用于更年期激素治疗。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有人游离雌三醇(FE3)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游离雌三醇(FE3)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 FE3 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 FE3 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.
