干扰素β（IFN-β）是一种多肽，通常由成纤维细胞产生，具有抗病毒和抗增殖的作用。IFN-β与它的受体结合，诱导出复杂的转录反应。在免疫细胞中（IFN-β在多发性硬化症中最可能的治疗效果的目标），IFN-β减少抗原呈递和T细胞增殖，改变细胞因子和基质金属蛋白酶（MMP）表达，并恢复抑制功能。IFN-β的治疗形式可以在细菌表达系统（IFN-beta1b）或哺乳动物细胞（IFN-beta1a）中产生。 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β干扰素(IFN-β)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β干扰素(IFN-β)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 IFN-β. 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 IFN-β 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.
