Fig. 2. Subcellular localization of the various constructs characterized in the present work as visualized by laser confocal microscopy. COS-7 cells were transfected with the various constructs, and the fluorescence was analyzed 36 hours after transfection. GFP fluorescence was visualized by confocal microscopy at an excitation wavelength of 488 nm. Bar, 50 µm.
