Characterization of H+ and HCO3- transporters in CFPAC-1 human pancreatic duct cells

Figure 4 Basolateral HCO₃^– uptake – changes in (A) ∆pH_i and (B) J(B) caused by the withdrawal of Cl^– and/or Na⁺. SE of the control groups (standard, black bar) is somewhat different for each of the respective ion-withdrawal groups. The SEs depicted on the standard bars are the maximum values observed. ^aP<0.05 and ^bP<0.01 vs control group ^dP<0.01 vs Cl^–-free group and/or ^fP<0.01 vs Na⁺-free group.
