Description	Llama IgG2b Fc, Tag Free (IGB-L5204) is expressed from human 293 cells (HEK293). It contains AA Glu 1-Ser 243 (Accession # AAX73259.1).
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. Ig gamma-2 chain Fc region contains two constant regions of IgG2 H chain (CH2, CH3).
Molecule	IgG2b Fc
Exp Region	Glu 1-Ser 243
Characteristics	This protein carries no "tag". The protein has a calculated MW of 27.3 kDa. The protein migrates as 35-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin	1.0 EU per μg
Buffer	Tris with Glycine, Arginine and NaCl, pH7.5
Stability	● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution._x000D_For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Protectant	trehalose
