FIG. 4.
Na enhances R-induced lytic infection in a cell-line-dependent manner. AGS R-KO (A), BL30 R-KO (B), or LCL R-KO (C) cells were transfected with pRC (vector), pRC-FLAG-BRRF1 (Na), pSG5-R (R), or pRC-FLAG-BRRF1 and pSG5-R (Na+R). Cells were harvested at 48 h posttransfection, and 35 μg of protein was immunoblotted with the indicated antibodies. Densitometric analysis was performed with NIH Image software. AGS(−), EBV-negative AGS cells.
