一般說明
免疫球蛋白(Ig)属于免疫球蛋白超家族(IgSF)。Ig一般由两条重(H)链和两条轻(L)链组成。轻链可以是κ或λ链。每条链包含一个NH2末端“可变”(V)区和一个或多个COOH末端“恒定”(C)区。每个区都由两个通过二硫键′固定′起来的夹心式β折叠片组成。根据重链C结构域Ig主要有五种,分别是IgM、IgG、IgA、IgD和IgE同种型。IgG可以分为四个亚类:IgG1、IgG2、IgG3和IgG4。每个亚类都有不同的生物特性。
應用
山羊源抗人 IgG(Fab 特异性)F(ab′2)片段抗体可用于酶联免疫吸附测定(ELISA)和生物传感器方法。
生化/生理作用
IgG抗体亚型是免疫系统中最丰富的血清免疫球蛋白。它由B细胞分泌,存在于血液和细胞外液中,可防止细菌、真菌和病毒引起的感染。母体IgG可通过胎盘转移至胎儿,胎盘对新生儿免疫防御感染至关重要。
免疫球蛋白G(IgG)由木瓜蛋白酶消化,并产生两个可结合抗原的Fab片段和一个Fc片段。IgG由胃蛋白酶裂解成一个Fc片段和一个可以交联并结合抗原的二聚体F(ab)2。
