Of several thousand peptides presented by the major histocompatibility molecule HLA-A2. 1,
at least nine are recognized by melanoma-specific cytotoxic T lymphocytes (CTLs). Tandem
mass spectrometry was used to identify and to sequence one of these peptide epitopes.
Melanoma-specific CTLs had an exceptionally high affinity for this nine-residue peptide,
which reconstituted an epitope for CTL lines from each of five different melanoma patients
tested. Recognition by multiple CTL lines suggests that this may be a promising candidate …
