甲状腺结合球蛋白(TBG)是一种球蛋白,由 SERPINA7 基因编码。它在循 环中结合甲状腺激素。它是三种运输蛋白(以及转甲状腺素和血清白蛋白) 之一,负责在血液中携带甲状腺激素甲状腺素(T4)和三碘甲状腺原氨酸 (T3)。在这三种蛋白质中,它对 T4 和 T3 具有最高的亲和力,但相对于转 甲状腺素和白蛋白的浓度最低,后者在循环中也结合 T3 和 T4。尽管浓度低, 但 TBG 携带血浆中的大部分 T4。由于血液中 T4 和 T3 的浓度非常低,TBG 的配体饱和度很少超过 25%。与转甲状腺素和白蛋白不同,它对 T4/T3 具有 单一结合位点。它主要在肝脏中合成为 54-kDa 蛋白。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人甲状腺结合球蛋白(TBG)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甲状腺结合球蛋白(TBG)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 TBG. 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 TBG 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.
