Figure 5From: A link of Ca2+ to cAMP oscillations in Dictyostelium: the calmodulin antagonist W-7 potentiates cAMP relay and transiently inhibits the acidic Ca2+-storeInduction of vesicular Ca2+-release by W-7. Vesicular Ca2+-uptake was measured as described in Materials and Methods. Addition of 400 μM ATP initiated Ca2+-uptake. Following a Ca2+ calibration pulse W-7 was added. One out of ten independent experiments is shown.Back to article page
