Analysis Note
蛋白质浓度应在重组后通过 280 nm 处的吸光度（E1%/280 = 14）测定。
Application
纯化的 IgG 可用作各种免疫测定中的参考抗原、标准品、封闭剂或包被蛋白，包括 ELISA、斑点免疫结合、蛋白免疫印迹、免疫扩散、免疫沉淀和免疫电泳等。其他应用包括作为制备免疫原和固相免疫吸附剂的起始材料。
Biochem/physiol Actions
IgG 介导经胎盘转运并参与二次免疫反应。IgG 激活补体系统的经典途径。它中和病毒颗粒和毒素。IgG 在抗体依赖性细胞介导的细胞毒性（ADCC）和吞噬作用中起关键作用。它可能与过敏有关。它具有最长的血清半衰期。
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。
