Differential T cell responsiveness toward gp100 APLs is related to TCR’s ability to bind gp100/HLA-A2 complexes. TCR-engineered T cells were stained with titrated amounts of PE-conjugated peptide-MHC multimers (range: 400–12,5 nM peptide-MHC complexes) and analyzed via flow cytometry. The gp100-HLA-A2 multimers comprise either gp100 wt peptide or APLs A3 and S4S6. The BMLF-1-HLA-A2 multimer served as a negative control. Binding of peptide-MHC multimers is analyzed as described in Section “Flow Cytometry and Cell-Sorting” and indicated in percentage. Percentages correspond to marker-positive T cells. Results of one (out of two) representative experiment are shown based on the mean value of triplicate data points.
