Fig. 1. Subcellular distribution of GFP-Rab11 in K562 cells. K562 cells were
transfected with the plasmid pEGFP (control) or with the constructs
pEGFP-Rab11wt, pEGFP-Rab11Q70L and pEGFP-Rab11S25N. The stably transfected
cells were mounted on coverslips and immediately analyzed by fluorescence
microscopy without fixation using an inverted microscope (Nikon Eclipse TE
300, Germany) equipped with a filter system (excitation filter 450-490,
barrier filter 515). Images were obtained with a CCD camera (Orca I,
Hamamatsu) and processed using MetaMorph 4.5 (Universal Images
Corporation).
