5x105 of DC3.2-Rab39a cells were induced to express Rab39a overnight with 1 µg/ml dox in a 6 well plate. Cells were fed at 1 bead/cell of biotinylated-6µm magnetic beads for the indicated lengths of time. Magnetic-bead-phagosomes were isolated using the listed protocol. Phagosomes were washed and stained for Rab39a (HA-tag). Representative data for 3 independent experiments.
