Comparison of myoplasmic calcium movements during excitation–contraction coupling in frog twitch and mouse fast-twitch muscle fibers
Single twitch fibers from frog leg muscles were isolated by dissection and micro-injected with furaptra, a rapidly responding fluorescent Ca(2+) indicator. Indicator resting fluorescence (F(R)) and the change evoked by an action potential (ΔF) were measured at long sarcomere length (16°C); ΔF/F(R) w...
