Osmolarity plot for TC (A) and E17βG (B) in SER of Wistar rat liver.

Uptake of TC (1 μM) or E17βG (5 μM) was measured after an incubation time of 10 min at 37 °C at an inward positive membrane potential as described in 2.5.1.5. Outside osmolarity (Osm) was increased by adding sucrose ranging from 50 to 800 mM. Data (mean ± SD and linear regression analysis) are shown for a representative sample of 2 independent experiments.
