Biotinylated Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQC) Complex Protein (Monomer, MALS & SPR verified)

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.

Product Specifications

Background

Specifications

Biotinylated Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQC) Complex Protein is produced by co-expression of HLA and B2M loaded with NY-ESO-1 peptide. This 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 13.8 kDa. The protein migrates as 40-43 kDa and 13 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
