CD58,即淋巴细胞功能相关抗原3(LFA-3),是一种在抗原呈递细胞(APC)上表达的细胞粘附分子,特别是巨噬细胞。它与T细胞上的CD2(LFA-2)结合,对加强T细胞和专业抗原呈递细胞之间的粘附很重要。这种粘附发生在T细胞激活前T细胞和抗原呈递细胞之间短暂的初步接触中,当时T细胞在淋巴结中游荡,寻找T细胞受体反应的肽:MHC复合物的APC表面。CD58基因的多态性与多发性硬化症的风险增加有关。CD58在结直肠肿瘤启动细胞(CT-ICs)的调节中起作用。因此,表达CD58的细胞已成为肿瘤发生中的一个感兴趣的细胞。 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CD58分子(CD58)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CD58分子(CD58)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 CD58. 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 CD58 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.
