  • 출처
    Llama IgG2b Fc, Tag Free (IGB-L5204) is expressed from human 293 cells (HEK293). It contains AA Glu 1-Ser 243 (Accession # AAX73259.1).
    Predicted N-terminus: Glu 1
  • 분자 표징
    Online(Glu 1-Ser 243) AAX73259.1

    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.

  • 내독소
    Less than 1.0 EU per μg by the LAL method.
  • 순도

    >90% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • 레시피

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • 백그라운드
    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).
