assays A of 108 copies of the genome of viral RNA after monoazide treatment without photoactivation (A), after monoazide treatment without photoactivation followed by QIA-quick purification (B), after monoazide treatment with photoactivation followed by QIA-quick purification (C). Mean values ± SD (n=3). Lastly, optimal PMA / EMA concentrations were determined on viral RNA samples after dye treatment including photoactivation and purification buy AZD1480 steps. The effects of dye (concentrations of 10 to 200 μM) were determined by measuring the decrease in RNA quantification by RT-qPCR (Table 1C). PMA at 50 μM enabled the Akt inhibitor highest reduction of the RT-qPCR signal for HAV RNA (− 3.16 log10) and PMA at 100 and 200 μM respectively enabled the highest reductions of the RT-qPCR signal for RV (SA11) (− 3.58 log10) and RV (Wa) (− 2.52 log10). EMA was still found to be less efficient than PMA treatment for all the viral RNA tested. These data showed that PMA and EMA are able to bind to viral RNA upon photoactivation making the RNA unavailable for amplification by RT-qPCR, although excess dye concentrations can inhibit RT-qPCR assays. The effectiveness of PMA

and EMA treatments depends on the type of dye, the concentration of the dye and the viral RNA type, although enough PMA was found to be the most effective dye for the three viral RNA tested. Optimization of pretreatment combining dyes and surfactants before RT-qPCR assays for the selective detection of infectious viruses Determination of optimal PMA / EMA concentrations Table 2 shows the results of experiments conducted with viruses (HAV and RV (Wa, SA11)) to optimize a specific procedure based on dye treatment for selective detection of the viral RNA from infectious viruses using RT-qPCR assays A.
