Peak CD8 T-cell response determined by KP9/Mane-A*10 tetramer, expressed as percentage of all CD8 T cells.
Common epitopes identified are in bold.
The NP401-423 response was mapped to minimal epitope NP402-410 (SAGQISIQP, SP9) as shown in Fig. 4B.
Pool of 10 overlapping peptides, not finely mapped.
Studied only for responses to epitopes already mapped in animals 5821, 5827, 086B, and 8305.
