Fig. 3. The µstpCys element retains ssYFP in the ER. COS-7 cells were transfected with vectors encoding Myc-tagged ssYFP (myc), ssYFP-µstpCys (Cys) or ssYFP-µstpSer (Ser), together with galactosyl transferase-CFP (GalT-CFP). YFP (left panels) and CFP (middle panels) were visualized by confocal fluorescence microscopy individually or as merged images (right panels). Bar, 5 µm.
