Fig. 4. Overexpression of LGP85 does not cause enlargement of lysosome, but results in formation and accumulation of the late endosome-lysosome hybrid organelle. To label lysosomes, COS cells were incubated with Texas-Red dextran for 4 hours and chased for 20 hours. After that, cells were transiently transfected with LGP85 and fixed at 12 (A-C), 24 (D-F), and 36 (G-I) hours after transfection, followed by staining for LGP85 (A,D,G, green). Cells were visualized by confocal microscopy. The right columns show the merged images of LGP85 (green) and dextran (red).
