From: Glutathione-related substances maintain cardiomyocyte contractile function in hypoxic conditions
Changes in the concentration of free intracellular Ca2+ in isolated rat cardiomyocytes during electric stimulation (1 Hz) at normal oxygen level (buffer saturated with carbogen 95% O2 and 5% CO2) and under hypoxic conditions (buffer saturated with 95% N2 and 5% CO2). 10 sec fragments of the records, at 2 min of normoxia or hypoxia, are given. The ordinate shows the fluorescence intensity of Fluo-4 in arbitrary units (a.u.).
