Time and dose-dependent effects of Fab on the intracellular Ca2+ activity. Confocal Ca2+ imaging of permeabilized VMs used Fluo-4 Ca2+ indicator under the line-scan mode. Baseline was obtained in the absence of Fab under the free [Ca2+] of 200 nM. A. Ca2+ images was obtained at various time points (top) after Fab exposure (100 µg/ml). (B) Ca2+ images was obtained after addition of Fab sequentially (top) at the time interval of 15 min. Plots were average of at least 4 VMs.
