Background

The MAGE A4 antigen is a cancer-testis antigen and is expressed intracellularly in various solid tumor tissues, MAGE A4230-239 peptide (GVYDGREHTV) is a cytotoxic T lymphocyte (CTL) epitope presented by HLA-A2 The Human HLA-A*0201 MAGE-A4 (GVYDGREHTV) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M, and GVYDGREHTV peptide of the MAGE-A4.

Specifications

Biotinylated Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Complex Protein is produced by co-expression of HLA and B2M loaded with MAGE-A4 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 42-45 kDa and 15 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
