Plasma viral RNA levels and PBMC-associated viral DNA loads in pig-tailed macaques challenged with SHIVDH12 after the administration of neutralizing IgG at 6 or 24 h after virus inoculation. The number of SHIVDH12 RNA copies in the plasma or PBMC-associated viral DNA was determined over a 4- to 7-month period by quantitative RT-PCR or DNA PCR, respectively. Control animals PT98P033 and PT98P056 received IgG prepared from an HIV-1-uninfected chimpanzee.
