Figure 6. (A) Microtubules growing off of pellicles in X. laevis egg extracts. (A, top) Heavy labeling with Alexa-488 tubulin allows all microtubules to be visualized, but individual filaments cannot be resolved. (A, bottom) The same region as in A with single molecule level Alexa-647 tubulin. Bar, 10 μm. (B) Distributions of tubulin lifetimes from pellicles (pellicles, blue) and unperturbed spindles (control spindles, green) are very similar. Best fits to Equation 1 are displayed for pellicles (red, τ = 71 ± 9 s) and spindles (black, τ = 64 ± 6 s). Image published in: Needleman DJ et al.
