免疫球蛋白IgG，由B淋巴细胞激活的浆细胞分泌产生。是人血清中丰富的蛋白质之一。IgG又分为四种亚型（IgG1,IgG2，IgG3，IgG4）,最主要的是IgG1,而IgG4占总IgG的5%左右。

产品说明

IgG1 immunoglobulin is most prevalent (>50%) and the IgG4 variety constitutes less than 5%. IgG4 has disulfide bonds linking the heavy chains unsteadily, allowing their separation and forming 2 antigen-binding sites, so that the bispecific antibody is asymmetric with an unclear in vivo role. IgG4 interacts with the Fc portion of IgG1–3 and not through the Fab-Fc, as occurs with other immunoglobulins, and has rheumatoid factor activity. Therefore, IgG4 has little or no cross-reactivity between antigens and rarely forms immune complexes having no complement activation capacity
