Figure 2. Rescue of anion exchange activity of H723R-pendrin by Arf1-Q71L.

Figure 2

The Cl/HCO3 exchange activity was measured by recording pHi as detailed in Methods. A clone of HEK 293 cells that exhibited minimal intrinsic anion (Cl/HCO3) exchange activity (a) was transfected with the indicated plasmids (bd) and then anion exchange activity was analysed. The quantitation of multiple experiments is depicted in e. Blockade of ER-to-Golgi trafficking by Arf1-Q71L significantly increased Cl/HCO3 exchange activity in cells expressing H723R-pendrin. **P<0.01 by unpaired Student's t-test, the number of replicates (n) is presented in each lane.
