  • Source
    Biotinylated Human HLA-A*11:01&B2M&EGF R (KITDFGRAK) Complex Protein(HLR-H82Eb) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*11:01) & Ile 21 - Met 119 (B2M) & KITDFGRAK peptide (Accession # Q5S3G3-1 (HLA-A*11:01) & P61769 (B2M) & KITDFGRAK).
    Predicted N-terminus: Gly 25 & Ile 21
  • Molecular Characterization

    Biotinylated Human HLA-A*11:01&B2M&EGF R (KITDFGRAK) Complex Protein is produced by co-expression of HLA and B2M loaded with EGF R peptide.

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

    The protein has a calculated MW of 36.0 kDa and 11.7 kDa. The protein migrates as 40-43 kDa and 11 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 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. The Human HLA-A*1101 & B2M & EGF R (KITDFGRAK) protein is a complex of HLA-A*1101 of the MHC Class I, B2M, and KITDFGRAK peptide of the EGF R.
