FIG. 5.

Chlorpromazine treatment does not inhibit influenza virus infection. (A) HeLa cells were infected with SFV for 5 h, and infection was monitored using monoclonal antibody E1-1. (B) HeLa cells were infected with influenza virus for 4 h, and infection was monitored using an anti-NP monoclonal antibody. Cells were treated with either 25 nM bafilomycin A or 10 μg of chlorpromazine/ml during both the adsorption and incubation periods. Infection was monitored by FACS analysis. Key indicates treatment of cells. Background was determined by residual antibody staining on uninfected cells.
