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

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 (SLLMWITQV) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M and SLLMWITQV peptide of the NY-ESO-1.

Background

Specifications

APC-Labeled Human HLA-A*02:01&B2M&NY-ESO-1 (SLLMWITQV) Tetramer Protein is assembled by biotinylated monomer and APC-labeled 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™) .
