Fig. 8From: HCO3 −-dependent transient acidification induced by ionomycin in rat submandibular acinar cellsIM-induced [Ca2+]i increase after re-introduction of Ca2+ in HCO3 −-free solution. The re-introduction of Ca2+ increases [Ca2+]i in rat submandibular acinar cells stimulated with 5 μM or 1 μM IM. Increases in [Ca2+]i in the absence of HCO3 − were similar to those in the presence of HCO3 −. a 5 μM IM, b 1 μM IMBack to article page
