Raw264.7 cells were transfected with plasmids expressing eGFP(N-term)-WT-Rab10 or Q68L-Rab10 (GTP-locked). (C, D) Cells were further stained for (C) EEA1, or (D) Lamp1, which was detected with Cy5 dye (show as red signal). Representative photomicrographs are from 25 cells each analyzed for each condition from n=3 biologically independent experiments. White bounding boxes are magnified in "High Mag" panels that show individual vesicles. Positive co-localization signal (see Methods) is indicated in bounding boxes labeled as "CoLoc." Colocalized pixels are shown in white. Scale bars are 10 μm, or 1 μm in "Hig Mag" panels and "CoLoc" panels. White arrow heads indicate Rab10 vesicles colocalized with the indicated marker.
