超氧化物歧化酶(SOD,EC 1.15.1.1)是一种交替催化超氧化物(O-2)阴离子自由基歧化(或分离)为正常分子氧(O2)和过氧化氢(H2O2)的酶。超氧化物是氧代谢的副产物,如果不加以调节,会对细胞造成多种损害。因此,在几乎所有暴露于氧气的活细胞中,SOD 都是一种重要的抗氧化防御物质。植物乳杆菌和相关乳酸菌是一个例外,它们利用细胞内的锰来防止活性 O-2 造成的损害。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有大鼠超氧化物歧化酶(SOD)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大鼠超氧化物歧化酶(SOD)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 Rat SOD. 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 Rat SOD 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.
