HEK-293CellsIgG2IsotypeControl
詳情介紹:
Isotype | IgG2 |
Characteristics | This protein carries no "tag". The protein has a calculated MW of 25.7 kDa. The protein migrates as 33-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. |
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. |
ProductDetails: Biological Activity Comment | Biological Activity: Measured by its ability to bind rhCD32a (Catalog # CDA-H5221) in a functional ELISA. |
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 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). |
Molecular Weight | 25.7 kDa |
UniProt | P01859 |
Research Area | Secondary Antibodies |
Application Notes | Optimal working dilution should be determined by the investigator. |
