^aAll Cl⁻ and HCO₃ ⁻ transport rates are in μM/min recorded upon the first Cl⁻ removal of oocytes incubated in HCO₃ ⁻-buffered media (Cl_in ⁻/HCO_3out ⁻ exchange).

^bThe first sets of Cl⁻ and HCO₃ ⁻ transport and the ratios for each transporter were taken from Fig. 1 B.

^cThe second and third sets for slc26a3 were taken from Fig. 2 (A and C, respectively).

^dThe second set for slc26a6 was taken from Fig. 8 A.

^eMean ± SEM.
