CHO cells were tested for their susceptibility to LacZ(RD114), LacZ(SRV-2), and LacZ(BaEV) pseudotype viruses before treatment with tunicamycin [(−)Tunic] and after treatment of the cells with 250 ng of tunicamycin/ml [(+)Tunic] for 24 h. The viruses used in these assays had titers of approximately 105 CFU/ml when examined in human TE671 cells.
