We observed mostly cytoplasmic, some nuclear, but rarely both, GFP
fluorescence in RAT2 fibroblasts transfected with the pGreenLantern GFP
construct (no NLS). The fibroblasts were FACs sorted 2 weeks after
transfection and it was pretty surprising to see some clones expressing
it in the nucleus and others (more as one would expect) in the cytoplasm.
Just an observation..... not a publication....... :)
