Characteristics of clone 2G12. The procedure used for clone 2G12 was the same as the one described in Fig. 2. a Recognition of EBV-B cells loaded with recombinant gB-expressing bacteria by CD4⁺ T-cell clone 2G12. b Recognition of gB overlapping peptides by CD4⁺ T-cell clone 2G12. c Identification of the minimal gB epitopes recognized by CD4⁺ T-cell clone 2G12. d Inhibition of the gB peptide recognition by anti-HLA-DP, -DQ or -DR Abs. e HLA-class II restriction analysis of the gB epitope recognized by CD4⁺ T-cell clone 2G12
