Unconjugated Human HLA-A*33:03&B2M&EGF R (HVKITDFGR) Complex Protein (Monomer, MALS verified)

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*3303 & B2M & EGF R (HVKITDFGR) protein is a complex of HLA-A*3303 of the MHC Class I, B2M, and HVKITDFGR peptide of the EGF R.

Background

Specifications

Unconjugated Human HLA-A*33:03&B2M&EGF R (HVKITDFGR) Complex Protein is produced by co-expression of HLA-A*33:03 and B2M loaded with EGF R peptide. This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™), and it is not biotinylated. The protein has a calculated MW of 36.2 kDa and 13.8 kDa. The protein migrates as 40-43 kDa and 12 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
