as an independent technique to determine whether and for how long ion flux through the anion exchanger is actually enhanced by exposure to hypertonicity , fluorescence measurements of n- ( 2-aminoethylsulfonate ) -7-nitrobenz-2-oxa-1,3-diazole ( nbd-taurine ) , a substrate of the anion exchanger in red blood cells , have been made in intact necturus gallbladder .
