MAGE-3 Antigen (271-279),human

MAGE-3 Antigen (271-279), human is a synthetic research peptide in the MAGE tumor-antigen peptide family. MAGE-family proteins are cancer-testis antigens from which multiple HLA-restricted cytotoxic T-lymphocyte epitopes have been defined. Synthetic MAGE peptides have been used to identify tumor-reactive CTL, compare HLA-binding properties, and measure peptide-specific T-cell responses. The immunological relevance of an individual MAGE peptide depends on the exact MAGE family member, residue range, sequence, and restricting HLA allele.

• MAGE-specific T-cell assays
• HLA peptide-binding studies
• tumor-antigen epitope mapping
• CTL induction and recognition studies
• native-versus-modified epitope comparisons

For antigenic peptides, MHC/HLA restriction, species, viral strain or tumor-antigen isoform, residue numbering, sequence substitutions, and chemical modifications can materially affect peptide binding and cellular recognition. The exact construct should therefore be matched to the intended assay and the reference sequence used in the experimental system.
