  • Synonym
    EGFR,ERBB,ERBB1,HER1,PIG61,mENA
  • Source
    Human EGF R, Llama IgG2b Fc Tag(EGR-H5259) is expressed from human 293 cells (HEK293). It contains AA Leu 25 - Ser 645 (Accession # P00533-1 ).
    Predicted N-terminus: Leu 25
  • Molecular Characterization
    EGF R Structure

    This protein carries a llama IgG2b Fc tag at the C-terminus

    The protein has a calculated MW of 96.4 kDa. The protein migrates as 115-150 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.01 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.

  • Background
    The epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is the cell-surface receptor for members of the epidermal growth factor family (EGF-family) of extracellular protein ligands. The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Mutations affecting EGFR expression or activity could result in cancer.
