Using rat [3-cells we present evidence that Sr 2+ and Ba 2+, like Ca 2+, support depolarization-induced increases in membrane capacitance which reflect insulin granule exocytosis. Even with identical total charge entry, Sr 2+ and Ba 2+ are 3-5 and 20-fold less effective than Ca 2+ in supporting rele
