Localization of GFP in keratinocytes on tattooing at 1.5 mm for 20 sec per 50 mm2 with a 5 mg/ml concentration of H2B-GFP-encoding DNA, visualized by confocal laser scanning microscopy. GFP expression (left) is clearly localized to the nucleus, confirming that this cell type was directly transfected on DNA tattooing.
