    HLA-A*0201 & B2M & p53 (HMTEVVRRC)
  • Source
    Human HLA-A*02:01&B2M&p53 (HMTEVVRRC) Tetramer Protein(HLP-H52H5) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & HMTEVVRRC peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769-1 (B2M) & HMTEVVRRC).
    Predicted N-terminus: Gly 25 & Ile 21
  • Molecular Characterization

    Human HLA-A*02:01&B2M&p53 (HMTEVVRRC) Tetramer Protein is assembled by biotinylated monomer (HLP-H82E4) and streptavidin.

    Biotinylated Human HLA-A*02:01&B2M&p53 (HMTEVVRRC) Complex Protein is produced by co-expression of HLA and B2M loaded with p53 peptide. Biotinylated Human HLA-A*02:01&B2M&p53 (HMTEVVRRC) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

    The protein has a calculated MW of 36.3 kDa and 11.7 kDa. The protein migrates as 40-43 kDa, 13 kDa and 10 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

 HLA-A*0201 & B2M & p53 (HMTEVVRRC) ELISA

Immobilized Anti-HLA class I Antibody, Human IgG1 (W6/32) at 1 μg/mL (100 μL/well) can bind Human HLA-A*02:01&B2M&p53 (HMTEVVRRC) Tetramer Protein (Cat. No. HLP-H52H5) with a linear range of 0.5-16 ng/mL (QC tested).

  • Background
    TP53 has been recognized as a tumor suppressor. 50% of cancers carry a TP53 mutation while many others affect other pathway components. High-copy numbers of WT p53 peptide-MHC class I complexes were detected on tumor cells as compared to low copies on normal cells. The Human HLA-A*0201 p53 (HMTEVVRRC) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M, and HMTEVVRRC peptide of the p53.
