FIG. 2.

ncp BVDV does not affect induction of apoptosis by SFV. CaTe cells were either infected with ncp BVDV (1 to 2 PFU/cell) or left uninfected and were subsequently infected with SFV at ∼10 PFU/cell. Cells were harvested in sample buffer at hourly intervals from 2 to 8 h postinfection and were subjected to immunoblotting using an anti-PARP monoclonal antibody (11). (a) CaTe cells; (b) CaTe cells previously infected with ncp BVDV. M, mock-infected cells.
