Product Details

  • Synonyms

    HLA-A*0201 & B2M & hTERT (ILAKFLHWL)

  • Source

    PE-Labeled Human HLA-A*02:01&B2M&hTERT (ILAKFLHWL) Tetramer Protein (HLT-HP2H5) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & ILAKFLHWL peptide (Accession # AAA59606.1 (HLA-A*02:01) & P61769 (B2M) & ILAKFLHWL).

    Predicted N-terminus: Gly 25 & Ile 21

  • Molecular Characterization

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

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

Background

hTERT (human Telomerase Reverse Transcriptase), the catalytic subunit of telomerase, maintains telomere length to drive tumor cells’ unlimited proliferation. It is highly expressed in ~85-90% of cancers but silenced in most normal somatic cells. The peptide ILAKFLHWL (from hTERT residues 540-548) acts as a tumor-specific antigen. It binds to MHC class I molecule HLA-A0201 to form a surface complex on tumors, activating cytotoxic T lymphocytes (CTLs). The Human HLA-A*0201 hTERT (ILAKFLHWL) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M, and ILAKFLHWL peptide of the hTERT.
