Lattice diffusion of CLIP-170(H2)–GFP protein (a carboxyl truncation of the plus end microtubule tracking protein CLIP-170). The movie shows pseudocolored overlaid images of rhodamine-labeled microt...

GMPCPP abolishes TIP activity of the CLIP-170(H2)–EB1 complex. The movie shows the localization of CLIP-170(H2)–GFP molecules (a carboxyl truncation of the plus end microtubule tracking protein CL...

TIP activity of Alexa 488–tagged EB1 protein (a plus end tracking protein). This movie shows pseudocolored overlaid images of rhodamine-labeled microtubules (red) and Alexa 488–tagged EB1 protein ...

TIP activity of CLIP-170(H2)–GFP (a carboxyl truncation of the plus end microtubule tracking protein CLIP-170) in the presence of EB1 protein (a plus end microtubule tracking protein). The movie sho...

Three dimensional data set acquired using a fast z-scan along the apical-to-basilar axis of a polarized epithelial cell in vitro to capture GFP-EB1 comets assosiated with the plus-end of actively poly...

TIRF time-lapse imaging of EB1-GFP (green) and mCherry-tubulin (red). EB1-GFP is seen on microtubule tips that grow to the cortex but does not accumulate on stable microtubule bundles at the equator, ...

Fluorescent micrograph of a Xenopus melanophore, showing microtubules (green), microtubule plus ends (red) and nucleus (blue). Honorable Mention, 2011 Olympus BioScapes Digital Imaging Competition®...

MT inhibition alters the location of the cell front. Time-lapse of a cell expressing RLC-D,D–GFP (a phospho-mimetic mutant of the RLC) on fibronectin in the presence of 1 mM nocodazole. Note the acc...

Microtubules in a Rac1(Q61L)-expressing PtK1 cell injected with Pak inhibitory fragment PBD/ID(H83L). Microtubules do not exhibit retrograde flow and undergo very little net growth. Epifluorescence i...

Microtubules in a control PtK1 cell at the edge of an epithelial cell island. Few pioneer microtubules rapidly grow into forming protrusions. The cell was microinjected with X-rhodamine-conjugated tub...
