Figure 5. Cellular localization of wild type and mutant VP1u.
HEK293T cells grown on cover glass were transfected with indicated plasmids; cells were fixed and analyzed by confocal microscopy at 48 h post-transfection. Green fluorescence showed the distribution of EGFP or EGFP-fused VP1u proteins. Nuclei were stained using DAPI. Confocal images were taken at a magnification of 40×.
