Agonist-activated Ca2+-fluxes in suspensions of iplA- and wild type amoebae. cAMP elicited reversible Ca2+-influx in the mutant (A) and in wild type ((B) and see ); measurements were done at t7–t7.5. Note the different doses of CaCl2 added for calibration. The time points of cAMP-addition (1 μM) and of AA-addition (6 μM) in the wild type are indicated by arrows.
