Figure 6From: Effect of black tea extract on herpes simplex virus-1 infection of cultured cells Viral titer determination using plaque assays. A. Plaque reduction assay results showing (from left to right wells): A549 cells exposed to media only, A549 cells exposed to HSV-1 and media and A549 cells exposed to HSV-1 and BTE. A549 cells were exposed to HSV-1 before being treated with BTE. B. Virus adsorption assay results showing (from left to right wells): A549 cells exposed to media only, A549 cells exposed to HSV-1 and media and A549 cells exposed to HSV-1 and BTE. A549 cells were exposed to HSV-1 treated with BTE. C . Virus attachment assay results showing (from left to right wells): A549 cells exposed to media only, A549 cells exposed to HSV-1 and media and A549 cells exposed to HSV-1 and BTE. A549 cells were treated with BTE before being exposed to HSV-1. D. Virus penetration assay results showing (from left to right wells): A549 cells exposed to media only, A549 cells exposed to HSV-1 and media and A549 cells exposed to HSV-1 and BTE. A549 cells were exposed to HSV-1 to allow attachment, but not penetration; cells were subsequently treated with BTE, then the virus was allowed to penetrate the cells.Back to article page
