Expression of PE38 packaged in vitro in four cell lines. Cells were transduced with a full reaction of PE38 plasmid DNA packaged in vitro (solid lines), and the number of cells was compared to mock transduced cells (dashed lines). Cells were counted every other day in order to monitor their viability. Cell lines were: HeLa cells (a), KB-3-1 cells (b), K562 human erythroleukemia cells (c), and .45 human lymphoblastoid cells (d).
