Fig. 11. GFP-RabD^Q67L rings multiparticle phagosomes. Cells expressing GFP-RabD^Q67L were incubated with RITC-labeled bacteria for 10 minutes in shaking suspension, washed and chased in fresh HL-5 while settling on coverslips. Live cells were examined using a fluorescent microscope in which images were taken in the rhodamine channel (A,C) and GFP channel (B,D). Bar, 3 µm. The arrows mark multiparticle phagosomes ringed with GFP-RabD.
