FIGURE 4.

Droplet size distribution and frequency of microtubule arrangements over droplet size. A, histogram of the size distribution of observed DOPC/DOPE/DOPG-monolayered droplets. The bar graph displays the relative frequencies of the categories of formed microtubule arrangements after 20 min in droplets of different size, containing 40 (B), 30 (C), or 50 μm (D) tubulin in standard droplet buffer. Droplets were assigned to the diameter bins (Ø) as indicated. Numbers in parentheses indicate the total count (N) of droplets for each size category.
