From: Probing the nuclear import signal and nuclear transport molecular determinants of PRV ICP22
The nuclear import mechanism of P-ICP22. a Fluorescence microscopy of COS-7 cells co-transfected with plasmid pP-ICP22-EYFP and plasmid encoding DN kβ1-ECFP, DN kα1-ECFP, M9M-RFP or Bimax2-RFP, respectively. b Fluorescence microscopy of COS-7 cells co-transfected with pP-ICP22-EYFP and pECFP-N1. The white arrowhead showed the nuclei in a cell that co-transfected with two plasmids. All scale bars indicate 10 um
