Figure 5. Calculations of the sizes of nuclei for actin fibrils.

(A) Dependence of normalized ThT fluorescence on time for actin [40]. (B) Dependence of L_rel on log T₂. (C) Dependence of L_rel on log [M_Σ]. The slope angle of the fitted line is approximately −0.01, i.e. L_rel is independent of log [M_Σ]. All L_rel values are also less than 0.2 which, according to the models of formation of fibrillar aggregates; means that the formation of actin fibrils occurs by the linear mechanism (see [39]). The size of the primary nucleus was calculated from the slope to be n=3.4±0.5.
