  • Source
    Alexa Fluor 647-Labeled Human HLA-A*11:01&B2M&WT-1 (FSCRWPSCQK) Tetramer Protein(HLW-HA2H4) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*11:01) & Ile 21 - Met 119 (B2M) & FSCRWPSCQK peptide (Accession # Q5S3G3-1 (HLA-A*11:01) & P61769 (B2M) & FSCRWPSCQK).
    Predicted N-terminus: Gly 25 & Ile 21
  • Molecular Characterization

    This protein carries a polyhistidine tag at the C-terminus.

    Alexa Fluor 647-Labeled Human HLA-A*11:01&B2M&WT-1 (FSCRWPSCQK) Tetramer Protein is assembled by biotinylated monomer and AF647-labeled streptavidin.

    Biotinylated Human HLA-A*11:01&B2M&WT-1 (FSCRWPSCQK) Complex Protein is produced by co-expression of HLA and B2M loaded with WT-1 peptide. Biotinylated Human HLA-A*11:01&B2M&WT-1 (FSCRWPSCQK) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

  • Background
    The Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) oncogene plays a critical role in the initiation and maintenance of pancreatic tumors and its signaling network represents a major target for therapeutic intervention. The Biotinylated Human HLA-A*1101 WT1 (FSCRWPSCQK) complex protein is a complex of HLA-A*1101 of the MHC Class I, B2M, and FSCRWPSCQK peptide of the KRAS.
