胆固醇 7α羟化酶(CYP7A1)又称胆固醇 7-α-单氧酶或细胞色素 P450 家族 成员 7A1,是一种酶,由 CYP7A1 基因编码,在胆固醇代谢中具有重要作用。 它是一种细胞色素 P450 酶,属于氧化还原酶类,将胆固醇转化为 7-α-羟基 胆固醇,这是胆汁酸合成的第一步和限制性步骤 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有小鼠胆固醇7α羟化酶(CYP7A1)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小鼠胆固醇7α羟化酶(CYP7A1)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 Mouse CYP7A1. 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 Mouse CYP7A1 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.
