Below you can find some pictures and movies of the microtubule cytoskeleton.
I have not updated this site for a long time, but I might upload some more microtubule related stuff soon..

This picture shows the microtubule network(red) and a MT plus-end binding protein named EB1(green),
which associates with the growing ends of MTs.
