Figure 11. Effect of voltage-dependent channel antagonists on MagT1-mediated currents. A, the antagonists nifedipine (10 µM) and nitrendipine (10 µM), or the agonist, Bay K8644 (10 µM), were added prior to determining Mg2+-evoked currents. B, summary of mean currents (I µA) with the respective inhibitors at a holding potential (Vm) of -125 mV (n=7). The analogues were added 5 min prior to voltage-clamping.
