Inhibition of sickling-induced45Ca++ uptake by dipyridamole and DIDS.
Ca++ influx rates were calculated as described in Figure3. The sickling-induced flux was calculated as the difference between the flux under oxygenated and deoxygenated conditions. DIDS concentration was 10 μM and dipyridamole concentration was 100 μM, at 10% hematocrit. Means and SDs of 5 experiments are shown.
