Figure 5.

The experimental protocol described in Figure 4 was repeated following exposure to BAPTA. (A) BAPTA abolished inward currents at early repolarization potentials (see Figure 4) to reveal a net outward current at these potentials. (B) There was little charge movement in CON cells but outward charge at positive membrane potentials in MCT myocytes. n = 4 CON and 3 MCT myocytes exposed to BAPTA ^****P < 0.0001, ^***P < 0.001, ^**P < 0.01, ^*P < 0.05 CON vs. MCT two way RM ANOVA.
