Fig. 6. Mechanical parameters of maximally Ca²⁺ (pCa 5.0) activated IFM fibers. (A) Elastic moduli as a function of frequency, (B) viscous moduli as a function of frequency, and (C) is power produced as a function of frequency. Values are mean ± S.E.M. for wild type, P{fln⁺}0.2 and P{fln⁺}2.2. There is no significant difference among the three Drosophila lines for any of the parameters.
