DC3.2 Rab39a KO cells were transduced with dox inducible mcherry-tagged Rab39a. Cells were plated in 35 mm glass bottom dishes and induced with 1 µg/ml dox. The next day, 1 µm latex beads conjugated with Alexa 488-NHS (1 bead/cell) were added. After 2 hours at 37oC, cells were imaged under a Leica TCS SP5 confocal microscope. Green = Alexa 488 labeled beads. Magenta = mcherry-Rab39a. Arrows highlight internalized beads surrounded by Rab39a. Scale bar = 10 µm. Representative image of two independent experiments.
