Figure 8.
Transients and flux elicited by a pulse train. The figure illustrates the kinetic analysis of Ca2+ flux for transients elicited by a train of depolarizing pulses (illustrated in A) to + 40 mV, at 30 Hz, lasting 2.5 s. (A and B) Fluorescence transients in WT and dCasq-null cells. (C and D) Corresponding evolution of [Ca2+]cyto and . (E) Evolution of amount released, R(t). The peaks of the increases in all magnitudes repeat the differences between WT and null illustrated in previous figures. Specifically, fluorescence and [Ca2+]cyto(t) can be compared with the corresponding records in Fig. 2, and R(t) with those in Fig. 7. ID: WT, 012809b_10; null, 020509b_8.
