(A) The effect of persistence length (ℓ_p) on filament force–extension behavior, as computed using numerical solutions of the model developed by MacKintosh and colleagues (Storm et al. 2005) (symbols) compared with an analytic model approximation (lines) (Palmer and Boyce 2008) fixing contour length (ℓ_c) to ℓ_c = 1.02 µm. (B) The effect of pretension on filament force–stretch behavior as computed by both methods. The end-to-end distance of a filament at a given condition is given by r.
