Fig. 9. Late phagosomes without membrane labeling by VatM-GFP. The membrane of the multi-particle phagosome in the upper part of this cell is labeled with VatM-GFP. TRITC-dextran has accumulated between yeast particles in this phagosome as well as at the bud necks. Below this large compartment are three phagosomes without VatM-GFP in their membranes (arrowheads); the presence of TRITC-dextran indicates that these are late phagosomes. The image in B is the same as that in A, but without the blue (phase contrast) channel. Bar, 10 µm.
