Resveratrol decreased MERS-CoV RNA and viral plaques. a MERS RNA level was monitored at 24 and 48 h.p.i. by real-time PCR after resveratrol treatment. Relative RNA levels were determined by comparing MERS only groups at each time point. GAPDH RNA was used as an internal control. b Quantification of plaque reduction assay of MERS-CoV titer after treated with resveratrol from 250 μM to 31.25 μM for 48 hours
