a

AT-2 SIV T-cell proliferation assay results are shown as a stimulation index. A minus sign indicates a stimulation index of ≤2.

b

SIV gag-specific IFN-γ ELISPOT assay results are shown as the number of spot-forming cells per 106 PBMC. The number of background spots in medium-only wells was subtracted from the number of spots in peptide-stimulated wells.

c

Detergent-disrupted SIV ELISA results are shown as the reciprocal of the highest positive dilution that was above the cutoff.

d

First PBMC sample in an animal that was vDNA positive by nested PCR for SIVgag.
