免疫球蛋白 G(IgG)是抗体的一种类型。IgG 是血液循环中最常见的抗体类型。 IgG 分子是由血浆 B 细胞产生和释放。每个 IgG 抗体都有两个准基。它由四 条肽链组成,包含两条相同的γ(gamma)重链,约 50 kDa,和两条相同 的轻链,约 25 kDa,因此是四元的四级结构。由此产生的四聚体有两个相同 的半边,共同形成 Y 型的形状。IgG 的 Fc 区在重链恒定区域的天冬酰胺 297 处有一个高度保守的 N-糖基化位点。连接到该位点的 N-糖基主要是复合物 类型的核心-岩藻糖基化双天线结构。此外,这些 N-聚糖中还有少量的双核 GlcNAc 和α-2,6-连接的唾液酸残基。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有猴免疫球蛋白G(IgG)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猴免疫球蛋白G(IgG)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 Monkey IgG. 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 Monkey IgG 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.
