||"[Researchers] used fluorescence videomicroscopy to follow the growth of
single tubes (Fig. 1A). The fluorescence intensity and, therefore,
the distribution of motors along the tube are inhomogeneous,
especially at the tip, where an excess of fluorescence can be seen..."
||"The average velocity, calculated over 20 different experiments
where a single tube was pulled from the GUV, was 0.09±0.06µ/s for an average membrane tension of 2?10^-4N/m."
