Mouse IgG2a Fc Protein, Tag Free

Source : 

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

 

Molecule : IgG2a Fc

 

Synonyms : IgG2A

 

Format : Powder

 

Category : Other Recombinant Proteins

 

Accession : CAC20702

 

Storage : -20℃

 

Shipping condition : Powder,RT

 

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 25-30 kDa under reducing (R) condition, and 50-60 kDa under non-reducing (NR) condition (SDS-PAGE).

 

Endotoxin Level : Less than 1.0 EU per μg by the LAL method.

 

Buffer : 50 mM Tris, 100 mM Glycine, pH7.5

 

Description :

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.
