唾液酸结合 Ig 样凝集素 2,也被称为 CD22,即分化簇-22,是一种属于凝 集素 SIGLEC 家族的分子。它存在于成熟 B 细胞的表面,在较小程度上存在 于一些未成熟 B 细胞。一般来说,CD22 是一种调节分子,可以防止免疫系 统的过度激活和自身免疫性疾病的发生。CD22 是一种糖结合的跨膜蛋白, 它与位于其 N 端的免疫球蛋白(Ig)结构域特异性地结合西亚里酸。Ig 结构 域的存在使 CD22 成为免疫球蛋白超家族的一员。CD22 的功能是作为 B 细 胞受体(BCR)信号传导的抑制性受体。 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CD22分子(CD22)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CD22分子(CD22)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 CD22. 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 CD22 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.
