Fig. 6From: Role of Ca2+ in the rapid cooling-induced Ca2+ release from sarcoplasmic reticulum in ferret cardiac musclesFraction of SR Ca2+ released by rapid cooling in the presence of either ATP or AMP-PCP. Ca2+ release was induced by rapid cooling in the presence of 4.6 mM ATP (left, n = 16) or in the presence of 4.6 mM AMP-PCP (right, n = 4). The amount of Ca2+ released by rapid cooling was normalised to the total amount of releasable Ca2+ in the SR (ordinate). Each bar represents the mean ± SEMBack to article page
