CA II dependence of basolateral membrane Na/nHCO3 cotransporter. Low HCO3 (2.62 mM) Ringer was perfused into the basal bath to record the pHi, TEP, and RT responses, first in the absence and then in the presence of 250 µM of basal DZA. After DZA washout, low basal bath [HCO3]-induced control response was obtained. Solid bars above the graphs represent solution changes from control Ringer as described in the legend to Fig. 2.
