The following HLA class I-restricted peptides were used for stimulation in an ELISPOT assay: HLA-A2 LMP2 epitope CLGGLLTML (CLG), HLA-A2 BMLF1 epitope GLCTLVAML (GLC), HLA-B8 BZLF1 epitope RAKFQLL (RAK), HLA-B8 EBNA3A QAKWRLQTL (QAK), HLA-B35 EBNA3B epitope AVLLHEESL (AVL), and HLA-B35 EBNA1 epitope HPVGEADYF (HPV).
†
The A11-DEP peptide was used as irrelevant peptide.
