Isotype IgG2a
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 25-30 kDa under reducing (R) condition, and 50-60 kDa under non-reducing (NR) condition (SDS-PAGE).
Purity >95 % as determined by SDS-PAGE.
Sterility 0.22 μm filtered
Endotoxin Level Less than 1.0 EU per μg by the LAL method.
Alternative Name IgG2a
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.
Molecular Weight 26.4 kDa
UniProt P01863
