Figure 5From: Inhibition of HIV-1 infection by TNPO3 depletion is determined by capsid and detectable after viral cDNA enters the nucleusStrategy for detecting cDNA from HIV-1 reporter virus after challenge of cells that had been previously transduced with HIV-1-based, lentivirus KD and rescue vectors. Schematic diagram showing methods of detection for HIV-1 late RT products (A), 2-LTR circles (B) and provirus (C) in KD cell lines. Identification of nascent cDNA is made possible by the presence of a loxP sequence engineered within a region of the 3'LTR U3 that is dispensable for retrotransposition.Back to article page
