pCa-tension curves. (a) pCa-tension plot comparing -, -, and nfTm-reconstituted muscle fibers. The tension data were fitted to (1), and the continuous lines are drawn based on best-fit parameters (Table 2). Error bars represent SEM. N = 14 for nfTm, N = 15 for and , and N = 9 for acetyl Tm. For acetyl Tm, the fitted parameters were reported in Lu et al. [13]. (b) pCa-stiffness plot, fitted to an equation similar to (1). (c) pCa-tension plot comparing nfTm and acetyl Tm.
