免疫球蛋白M(IgM)是分子量最大的免疫球蛋白,主要由脾脏和淋巴结中浆细胞分泌合成,分为IgMl和IgM2两个亚型。它具有强大的杀菌、激活补体、免疫调理和凝集作用,也参与某些自身免疫病及超敏反应的病理过程。IgM是脊椎动物产生的几种同种类型的抗体(也称为免疫球蛋白)中的一种,也是最大的抗体,它是最初接触抗原时出现的第一个抗体。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人免疫球蛋白M(IgM)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免疫球蛋白M(IgM)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 IgM. 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 IgM 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.
