VP2 protein is localized to the nucleus of the mammalian cells. HeLa (A) and CHO (B) cells both were transfected with GFP and VP2-GFP expressing plasmids (green). At 48 h post-transfection, the cells were fixed and stained with DAPI (blue). The distribution of GFP and VP2-GFP in the cells were followed by microscopy (phase) and fluorescence microscopy
