VpuEGFPW23A and VpuEGFP are localized to similar compartments. 293 cells were transfected with a vectors expressing either VpuEGFP or VpuEGFPW23A and either ER-DsRed2, Golgi-DsRed2 or Membrane-DsRed2 as described in the Materials and Methods section. At 48 hours, cells were processed for confocal microscopy. Figure 9A-I. 293 cells transfected with VpuEGFP. Panels A, D, and G are fluorescent micrographs showing expression of VpuEGFP. Panels B, E, H are fluorescent micrographs showing expression of DsRed2 proteins. Panels C, F, and I are a merge of the two panels to the left. Panels A-C. 293 cells transfected with VpuEGFP and ER-DsRed2. Panels D-F. 293 cells transfected with VpuEGFP and Golgi-DsRed2. Panels G-I. 293 cells transfected with VpuEGFP and Mem-DsRed2.
