Effect of divalent cations on cAMP production in HEK-293 cells stably transfected with AC9

No divalents	12.5 ± 0.5
Ca²⁺	9.9 ± 0.2*
Ba²⁺	11.3 ± 0.4
Mg²⁺	12.7 ± 0.6
Sr²⁺	11.1 ± 0.7

cAMP accumulation was evoked by the addition of 1 mmIBMX and 0.1 mm rolipram; data are expressed as multiples of the amount of cAMP found in cells not receiving PDE blockers, 80 ± 3 fmol/well in this experiment. Data are means ± SEM;n = 4 group. *p < 0.05 versus no divalents; one-way ANOVA, followed by Dunnett’s test.
