Fig 6. Comparison of releasable calcium.
Internal Ca2+ stores of cells were depleted by the application of 10 μM CPA in Ca2+-free Tyrode’s, which caused an increase in [Ca2+]i.both (A) in scrambled shRNA transfected and (B) cloneC1 cells. (C) Mean values of the integral of CPA induced calcium transients. Numbers in parentheses indicate the number of cells measured. Asterisks (*) mark significant (P<0.05) differences.
