  • Synonym
    IgG1
  • Source
    Mouse IgG Fc, Tag Free (IG1-M5208) is expressed from human 293 cells (HEK293). It contains AA Val 111 - Lys 324 (Accession # AAK53870.1).
    Predicted N-terminus: Val 111
  • Molecular Characterization
    Online(Val 111 - Lys 324) AAK53870.1

    This protein carries no "tag".

    The protein has a calculated MW of 24.3 kDa. The protein migrates as 28-30 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 51 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

Loaded Mouse FCGRT&B2M Heterodimer Protein, His Tag (Cat. No. FCM-M52W8) on NTA Biosensor, can bind Mouse IgG Fc, Tag Free (Cat. No. IG1-M5208) with an affinity constant of 17.9 nM as determined in BLI assay (ForteBio Octet Red96e) (QC tested).

  • Background
    Crystallizable fragments composed of the carboxy-terminal halves of both IMMUNOGLOBULIN HEAVY CHAINS linked to each other by disulfide bonds. Fc fragments contain the carboxy-terminal parts of the heavy chain constant regions that are responsible for the effector functions of an immunoglobulin (COMPLEMENT fixation, binding to the cell membrane via FC RECEPTORS, and placental transport). IgG1 Fc was reported has a novel role as a potential anti-inflammatory drug for treatment of human autoimmune diseases.
