FIG. 4.

Proliferative response of T cells derived from BB-immunized BALB/c mice to stimulation with BB or a panel of overlapping BB peptides. The first residues of every nine peptides are indicated in the x axis. Reactivity peaks are numbered to facilitate correlations with the sequence shown in Fig. 1; the numbers correspond to the first amino acid residues of the implicated peptide. The results are reported as the average of the proliferative index of triplicate sample experiments. This experiment is representative of three separate experiments.
