Recombinant S. typhimurium mediated expression of Apoptin. Hep-2 cells were infected with ST-rC-EGFP and were observed with fluorescence microscopy 24 hours after infection. (A). non-infected cells (mock). (B). ST-rC-EGFP infected cells (200x magnifications). (C). Western blotting analysis of recombinant S. typhimurium-mediated Apoptin (ST-rC-Apoptin) in Hep-2 cells. The cells were harvested at 24 hours after infection.
