Figure 6: Schematic representation of the levels of total (unspliced and spliced) intracellular HIV RNA in -infected PM1 cells that did not express an EGS [P(PM1)] or expressed EGS C1 (C1), C2 (C2), and TK1 (TK1). The RNA samples were isolated from cells at 48 hours after infection, and the levels of HIV RNA were determined using a real-time PCR assay. The values shown are the averages from three independent experiments.
