Parallel QVOA results in the presence or absence of raltegravir with CD4 lymphocytes from subject 219. Six replicates were performed for each serial threefold dilution of CD4 cells in the QVOA assay with (a, left row) or without (a right row) raltegravir in the culture medium throughout the assay shown on a log₁₀ scale. Culture supernatants were assayed for HIV RNA by real time (RT)-PCR. The asterisks on the lines of the replicates without raltegravir on day 14 indicate values for each well without raltegravir that exceeded the mean plus 5 standard deviations of the 6 replicates performed with raltegravir. b Displays the same data for day 14 to indicate visually that virions are induced in the presence of raltegravir (upper figure) and that amplification occurs in almost as many wells (lower figure)
