Fig. 2. Intracellular localization of EGFP–M9NLS and EGFP–M9G₂₇₄A molecules in mock-infected and poliovirus-infected cells. (A) HeLa cells were transiently transfected with plasmid pEGFP-M9NLS and mock infected or infected with poliovirus at 40 h after transfection and examined 4.5 h after infection. Labeling of panels is as described in Figure 1. (B) Same as in (A), except that cells were transfected with plasmid pEGFP-M9G₂₇₄A.
