Z-probes are localized in the nucleus. HeLa cells were transfected with the expression vectors for the Z-probe, Zmut-probe or NLS-EGFP. The cells were observed using a fluorescence microscope at 24 h after transfection. The Z-probe, Zmut-probe and NLS-EGFP proteins are shown in green. The nuclei were stained with DAPI (blue).
