Ionomycin effect on the rate of vesicle fusion in ATII cells. Relative fluorescence units (RFU) between single wells, at time 0, were converted to 100%. Carrier alone (controls) and Ionomycin in different concentrations were applied thereafter, between 1^st and 2^nd data point. Enlarged symbols at the end of the recordings indicate the endpoints taken for all subsequent analyses.
