维生素D受体（VDR又称钙三醇受体）是转录因子核受体家族的成员。钙三醇（维生素D的活性形式）与VDR结合，然后与视黄醇-X受体形成异二聚体，后VDR异二聚体进入细胞核并与基因组DNA中的维生素D反应元件（VDRE）结合。VDR的结合导致许多特定基因产品的表达或反抑制，它还参与microRNA指导的转录后机制。在人类，维生素D受体由位于染色体12q13.11的VDR基因编码。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人维生素D受体(VDR)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维生素D受体(VDR)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 VDR. 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 VDR 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.
