Fluorescence Lifetime Imaging of Propranolol Uptake in Living Glial C6 Cells

Figure 2

Time courses for uptake and release of propranolol from rat C6 glial cells. Uptake (a) was measured at 37°C from a solution containing SR-propranolol (100 μM, ■) and at 22°C with S-propranolol (100 μM, □). Cells previously loaded with propranolol (100 μM) were washed with phosphate-buffered saline to observe release (b) of SR-propranolol at 37°C (■) and 22°C (□).
