Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein (MALS verified)

  • Synonym
    HLA-A*02:01 & B2M & NY-ESO-1
  • Source
    Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein(HL1-H52E7) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-A*02:01) & Ile 21 - Met 119 (B2M) & SLLMWITQV peptide (Accession # A0A140T913 (HLA-A*02:01) & P61769 (B2M) & SLLMWITQV ).
    Predicted N-terminus: Gly 25 & Ser
  • Molecular Characterization

    Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein is assembled by biotinylated monomer (HL1-H82E4) and streptavidin.

    Biotinylated Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Complex Protein is produced by co-expression of HLA and B2M loaded with NY-ESO-1 peptide. Biotinylated Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) 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, 13.8 kDa and 13.3 kDa. The protein migrates as 42-45 kDa, 15 kDa and 14 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

The purity of Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein (Cat. No. HL1-H52E7) is more than 90% and the molecular weight of this protein is around 238-290 kDa verified by SEC-MALS.

Bioactivity-SPR
 HLA-A*02:01 & B2M & NY-ESO-1 SPR

Anti-NY-ESO-1 antibody captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein (Cat. No. HL1-H52E7) with an affinity constant of 1.15 nM as determined in a SPR assay (Biacore 8K) (QC tested).

  • Background
    NY-ESO-1, which is also well-known as New York esophageal squamous cell carcinoma 1, is an efficient target for cancer immunotherapy. This antigen is a member of cancer-testis antigens (CTAs) and is highly expressed in various cancers, including melanoma, ovarian, cervical cancer, etc. Adoptive T cell therapy with HLA-A2 restricted NY-ESO-1 transduced CD8+ T cells has improved the clinical response rates and overall survival of treatment-refractory melanoma patients. The Human HLA-A*0201 NY-ESO-1 (SLLMWITQC) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M and SLLMWITQC peptide of the NY-ESO-1.
