Figure 2From: Natural products that reduce rotavirus infectivity identified by a cell-based moderate-throughput screening assayEstablishment of internal controls: IFNα and IFNγ reduce rotavirus infectivity in the assay. Cells were treated with indicated amounts of each cytokine or a combination of both prior to infection. Infections were allowed to proceed for 18 hours and chemiluminescent measurement of reduction in rotavirus infectivity was performed as described in the text and in the legend to Figure 1. Error bars are standard errors of the means.Back to article page
