Time-lapse top/bottom 1,000-pixel images of the local membrane environment surrounding the insulin receptor. The whole time-lapse data set of PEG-Nile-Red labeled CHO cells expressing the ACP insulin receptor showing the top/bottom 1,000-pixel images exhibiting biggest (red) ZNCC changes and smallest (blue) 1,000 pixels of ZNCC in each ZNCC image (Fig. 6 A). Video corresponds to Fig. 7. Arrowheads show areas intensely blebbing and membrane ruffling. Video was acquired at 1 frame/10 s for 540 s and played back at 7 frames/s.
