Figure 4.

(a) Filament length dynamics for different strengths of multibody effect shown in different colors at concentrations below (left panel, c = 0.116 μM) and above (right panel, c = 0.120 μM) the critical concentration. (b) Filament growth rate (filled symbols) as a function of concentration of free actin is shown. Different colors represent different strengths of multibody effects. Open circles are experimental data taken from (34), originally extracted from experiments in (47). The inset shows the ratio of growth rate at a given strength of multibody effects compared to the growth rate at X = 0. To see this figure in color, go online.
