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

Figure 6 Basolateral HCO₃^– uptake – changes in (A) ∆pH_i (B) J(B) caused by application of H₂-DIDS, acetazolamide, ethoxyzolamide, STP and varying extracellular K⁺ concentration. Data are shown as mean ± SE (n = 6–11). SE of the control groups (standard, black bar) is somewhat different for each of the respective ion-withdrawal groups. The SE depicted on the control bar was the maximum values observed. ^aP<0.05 and ^bP<0.01 vs control group or ^cP<0.05 vs K⁺-free group. ATZ: acetazolamide; ETZ: ethoxyzolamide; STP: 1-N-(4-sulfamoylphenylethyl)-2,4,6-trimethylpyridine perchlorate. The SE depicted on the standard bars was the maximum values observed.
