PCR for LTR/gag region (detection of late reverse transcription products). PCR were performed on DNA extracted from cell cultures 21 days after infection attempt. Lane 1, positive control for PCR (DNA extracted from PBMC from a HIV-1-infected patient); lane 2, PCR negative control (water); lanes 3 to 6, DNA extracted from PBMC from a HIV-1-negative donor, exposed to 0, 100000, 200000 or 500000 virions respectively; lanes 7 to 10, DNA from KSY-1 cells exposed to 0, 100000, 200000 or 500000 virions respectively; lanes 11 to 14, DNA from KS-2 cells exposed to 0, 100000, 200000 or 500000 virions respectively; lane 15, DNA molecular weight marker.
