Figure 7. Sarcoplasmic Reticulum (SR) Ca2+ content is identical in WT and S2808A myocytes from Sham and MI hearts.

Figure 7

Caffeine-induced SR Ca2+ release was measured in WT and S2808A myocytes +/− Iso (10 nM) from sham or MI mice. A–B. Examples of Ca2+ transients elicited by 0.5Hz of electrical field stimulation (the first four traces) followed by Ca2+ transients induced by caffeine (the fifth large trace; the peak indicates SR Ca2+ content). C. Average amplitudes of caffeine induced Ca2+ transients −/+ Iso in WT and S2808A myocytes. *p<0.05 between sham and MI and # p<0.05 between −/+ Iso.
