免疫球蛋白E(IgE)是一种仅在哺乳动物中发现的抗体(或免疫球蛋白(Ig)"同种型")。IgE是由浆细胞合成的,它的单体由两条重链(ε链)和两条轻链组成,其中ε链含有4个类似Ig的恒定结构域(Cε1-Cε4)。IgE被认为是抵抗某些寄生虫感染的免疫反应的重要组成部分,包括曼氏血吸虫、螺旋毛虫和肝吸虫。它也被用于免疫防御某些原生动物寄生虫,如恶性疟原虫。IgE在I型超敏反应中也有重要作用,它表现为各种过敏性疾病,如过敏性哮喘、大多数类型的鼻窦炎、过敏性鼻炎、食物过敏,以及特定类型的慢性荨麻疹和特应性皮炎。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有大鼠免疫球蛋白E(IgE)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免疫球蛋白E(IgE)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 IgE. 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 IgE 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.
