FIG. 5.

RT activity in clones expressing sense or antisense RLI constructions. H9 cells transfected with the empty vector (○, VV), with the antisense RLI cDNA construction (◊, VAS), or with the sense RLI cDNA construction (□, VS) were infected with HIV-1. Virus production was monitored by supernatant RT assay every day. 100% is the RT activity observed in uninfected cells. Vertical bars refer to the standard deviations obtained with three independent experiments. Clones VV, VAS1, and VS1 are shown in panel A, and clones VV, VAS2, and VS2 are shown in panel B.
