Human IgG4 Fc Protein, Tag Free (MALS & SPR verified)

  • シノニム
    IGHG4
  • ソース
    Human IgG4 Fc, Tag Free (IG4-H5205) is expressed from human 293 cells (HEK293). It contains AA Glu 99 - Lys 327 (Accession # P01861).
    Predicted N-terminus: Glu 99
  • 分子特性
    Online(Glu 99 - Lys 327) P01861

    This protein carries no "tag".

    The protein has a calculated MW of 25.8 kDa. As a result of glycosylation, the protein migrates as 30-32 kDa under reducing (R) condition, and 28-30 kDa and 55-60 kDa under non-reducing (NR) condition (SDS-PAGE).

  • エンドトキシン
    Less than 1.0 EU per μg by the LAL method.
  • 純度

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • 成分

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

  • バックグラウンド
    Immunoglobulin G4 (IgG4) 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. Ig gamma-4 chain Fc region contains two constant regions of IgG4 H chain (CH2, CH3).
