FIG 1.

Animals vaccinated with m3KOΔnef are partially susceptible to intravenous (IV) challenge with SIVmac239. gag and nef qRT-PCRs were performed on plasma samples at the indicated times after intravenous SIVmac239 challenge. (A) Three animals with evidence of full-length nef. (B) Four animals without replicating full-length nef. Data for each animal are shown on independent plots. The horizontal dotted line at 50 copies/ml (copy equivalents [ceq] per milliliter) represents the limit of detection of the assay.
