Figure 1. Staurosporine released Ca²⁺ from the IP₃-independent Ca²⁺ store in rat submandibular acinar cells. (A) After the application of 10 µM carbachol, perfusate Ca²⁺ was removed, and 200 nM staurosporine was added in the continued presence of carbachol (n = 9). (B) As a control experiment, [Ca²⁺]_c was measured without the addition of staurosporine (n = 4). Fura-2-loaded cells were stimulated at the times indicated by the bars.
