Figure 1. Analysis of relaxation induced by photolysis of diazo-2 in skinned psoas fibres at 15 °C.

Figure 1

A, an example of relaxation induced in standard diazo-2 solution where F6.1pre/F4.0 = 0.44, Fpost/F4.0 = 0.04, ΔF/Fpre = 0.91, time constant of the fast phase of relaxation, kf = 32 s−1, time to shoulder (to) = 9 ms, half-relaxation time (t1/2) = 31 ms. B, an example of relaxation induced in the presence of M82Q TnC and a solution containing a low concentration of inorganic phosphate ([Pi]), where F7.0pre/F4.0(low[Pi]) = 0.58, Fpost/F4.0(low[Pi]) = 0.13, ΔF/Fpre = 0.78, time constant of the slow phase of relaxation, ks = 1.4 (F/ΔF) s−1, kf = 8 s−1, to = 100 ms, t1/2 = 185 ms.
