Figure 5. Effect of perifusion flow rate on islet oxygen.
Encapsulated islets were perifused at 180 µL/min in KRB containing 3 mM glucose. At time = 15 minutes, the flow rate was changed to 50 µL/min, and at time = 70 it was decreased back to 180 µL/min. This protocol was repeated after suppressing respiration by 3 mM KCN.
