Synergistic Effects of Sulfated Polysaccharides from Mexican Seaweeds against Measles Virus

Figure 6

Time of addition experiments. Antiviral activity of SP was tested at different times of infection and analyzed by syncytia inhibition assays. SPs were added at 60 min before infection and 0, 15, 30, 60, and 120 min after infection. The data are expressed as relative syncytia count (%) compared to that of untreated virus-infected control cells, which was defined as 100%. The data shown are the mean ± SD of triplicate experiments.
