FIG. 2.
Staining of CD8+ T cells with the HLA B7-NL9 (RSV-NP) tetramer. (A) Peptide-specific line used in assays shown in Fig. 1 from subject A (HLA type, A2/3 B7/51 Cw5/7). (B) PBMC from B7-negative subject E (HLA type, A34/68 B51/72 Cw2/16). (C) PBMC from B7-positive subject C (HLA type, A3/26 B7/38 Cw7/8). (D) PBMC from subject D (HLA type, 11/25 B7/18 Cw7/12). (Top right) A2-HIV Gag CTL clones from subject 161j (HLA type, A2/3 B7/60 Cw3/7). (Bottom right) Staining of the same CTL clone as above but using the A2-HIV Gag tetramer.
