Fig. 5. Confocal immunofluorescence studies of cav-1 and markers of different organelles in PC-3 cells. (A-L) PC-3 cells stably expressing BENE-myc were fixed and double-labelled with antibodies to cav-1 and: the early endosomal marker EEA1 (A-C); the lysosomal marker CD63 (D-F); the Golgi marker giantin (G-I); and lipid droplets stained with Nile red (J-L). Cells have been outlined for better visualization. Bars, 10 µm.
