髓样前体细胞抑制因子2(MPIF2)也被称为CCL24或嗜酸细胞趋化蛋白2（eotaxin-2），是一种由CCL24基因编码的蛋白质。它是属于CC趋化因子家族的一种小型细胞因子。它与趋化因子受体CCR3相互作用，诱导嗜酸性粒细胞的趋化性。在患有阿司匹林加重的呼吸道疾病（AERD）的患者中，如哮喘患者，MPIF2的水平已经升高了。血浆中MPIF2水平较低的人没有显示出发展阿司匹林诱导性哮喘的趋势。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有小鼠髓样前体细胞抑制因子2(MPIF2)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髓样前体细胞抑制因子2(MPIF2)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 MPIF2. 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 MPIF2 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.
