Mechanical parameters for single muscle fibers for Fig. 4

Fiber sample	Maximal tension	pCa50	n (Hill coefficient)
Untreated + DTT + TnC	279.67 ± 13.63	6.289 ± 0.071	4.670 ± 0.47
ES + DTT + TnC	224.30 ± 26.25	6.183 ± 0.004	1.601 ± 0.045
rRLC + DTT + TnC	270.24 ± 15.23	6.310 ± 0.048	3.154 ± 0.021
vRLC + DTT + TnC	275.31 ± 18.51	6.515 ± 0.015	2.244 ± 0.144

The tension is reported as kN/m². The values are the mean ± SE for four single fibers from two preparations. The difference pCa₅₀ for the untreated + DTT + TnC fibers in Table 2 compared with Table 1 is explained in Materials and Methods. ES + DTT + TnC fibers are rRLC-depleted fibers; rRLC + DTT + TnC are fibers reconstituted with rabbit RLC; and vRLC + DTT + TnC are fibers reconstituted with rat vRLC.
