(A) Formation of formazan measured as change in absorbance in wt and αMHC403/+ myocytes after addition of 10 μmol/l BayK(+) or BayK(-). (B) Mean ± SEM of increases in absorbance for all myocytes exposed to BayK(+), BayK(-), 10 μmol/l nisoldipine (Nisol), 5 μmol/l Ru360, 5 μmol/l ryanodine (RyR), or 20 μmol/l oligomycin (Oligo) as indicated. (C) Ratio of increase in absorbance after addition of BayK(-). The Kruskal-Wallis test was used for all comparisons. Abbreviations as in Figures 1 and 2.
