摘要: The Ca2+ -sensitive bioluminescent protein aequorin was microinjected into cells of frog atrial trabeculae to study intracellular calcium transients associated with excitation-contraction coupling. amplitude the signal increased extracellular concentration and stimulus frequency, but decreased stretch. Isoprenaline acetylstrophanthidin both amplitude, had strikingly different effects on time course signal.
