Background：Immunoglobulin G2 (IgG2) is a member of many immunoglobulin G developed and secreted by effective B cells.
In wake of cutting by pepsin, IgG is divided into two F(ab)s with one antigen binding site and a high conserved Fc segment.
The Fc segment bears a highly conserved N-glycosylation site.
There are two members of IgG2: IgG2a and IgG2b.
It was found that IgG2a was superior to IgG1 in activating complement.
The glycosylation of the circulating immunoglobulin-γ (IgG) antibody molecules changes in rheumatoid arthritis.
