Uniform transport of NgCAM-GFP
A 7 day old neuron expressing the membrane protein NgCAM tagged with GFP. The video shows a rapid playback (6X real time) of a 30 second recording. NgCAM-GFP vesicles move bidirectionally in and out of both the axon and the dendrites at an average rate of 1um/sec. However, NgCAM is polarized to the axonal cell surface.
