Fig. 7. Distributions of the number of events during a 98-second period in which the instant speed of each of 900 LAMP1-GFP-positive organelles within wild-type (open bars) or pale ear (closed bars) fibroblasts increased from less than 0.78 µm/second to reach or exceed this threshold speed. Insets, comparable distributions obtained for 600 organelles labeled with the LAMP1-mGFP variant construct within wild-type or pale ear cells. Numbers on the x-axis denote bin limits; the last bin on the right includes all values greater than 14.
