PE-Labeled Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Tetramer Protein

Streptavidin Protein - PE (STN-NP117, STN-NP119), supporting the assembly of your own MHC Tetramers!
  • Source
    PE-Labeled Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Tetramer Protein(HLP-HP2H3) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & KVLEHVVRV peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769-1 (B2M) & KVLEHVVRV).
    Predicted N-terminus: Gly 25 & Lys
  • Molecular Characterization

    PE-Labeled Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Tetramer Protein is assembled by biotinylated monomer and PE-labeled streptavidin.

    Biotinylated Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Complex Protein is produced by co-expression of HLA and B2M loaded with MAGE-A4 peptide. Biotinylated Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
