Figure 3

Depolarisation with elevated K+induces force and intracellular Ca2+ signals. Representative example (n = 3) of intracellular Ca2+ (ratio 340/380, RU, blue) and isometric force (red) of an aortic segment upon gradual elevation of external K+ from 5.9 mM to the values indicated on top of the figure. Both signals are shown in the right panel on an extended time scale for transitions from 15 to 20, from 20 to 25 and from 25 to 30. Black arrows indicate decrease of Cai2+ with accompanying increase of force.
