Lack of effect of a 5 ns pulse on [Ca2+]i in chromaffin cells treated with CPA, caffeine and ryanodine. (A) Schematic diagram showing the order in which cells were treated with CPA, ryanodine and caffeine to fully deplete the ER of Ca2+. (B) Representative traces of release of Ca2+ from the ER by caffeine (lower gray bar) in the continued presence of CPA and ryanodine (upper gray bar). (C) Averaged fluorescence traces ± s.e. (n = 46) showing the lack of effect of a 5 ns, 17 MV/m pulse (arrow) applied to cells treated according to the strategy depicted in (A) in the continued presence of CPA, ryanodine and caffeine (gray bar). Error bars not shown are within the thickness of the line.
