HCO(3) (-)-dependent transient acidification induced by ionomycin in rat submandibular acinar cells
{{output}}
Ionomycin (IM, 5 microM), which exchanges 1 Ca2+ for 1 H+, changed intracellular pH (pHi) with Ca2+ entry into rat submandibular acinar cells. IM-induced changes in pHi consisted of two components: the first is an HCO3--dependent transient pHi decrease, and th... ...
