These sequences were chosen for study because mass-spectrometric analysis ( MS ) of a CTL active HPLC peptide fraction eluted from immunoaffinity precipitated HLA-A2 molecule , revealed : ( a ) the presence of an ion with a mass-to-charge ratio ( m/z ) of 793 which was more abundant than other ions of similar masses ; ( b ) the tentatively reconstituted sequence of the ion 793 matched the sequence of peptide G76 .
