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.

Source: Mouse IgG2a Fc, Tag Free (IGA-M5207) is expressed from human 293 cells (HEK293). It contains AA Glu 98 - Lys 330 (Accession # CAC20702).

Format: Powder.

Tag: Native.

Expression System: HEK293.

Expression Region: Glu 98 - Lys 330.

Conjugate: Unconjugated.

Molecular Weight: 26.4 kDa.

Characteristics: This protein carries no "tag". The protein has a calculated MW of 26.4 kDa. As a result of glycosylation, the protein migrates as 30-35 kDa under reducing (R) condition, and 55-60 kDa under non-reducing (NR) condition (SDS-PAGE).
