Abrogation of the tight junctions modulates luminal acidification. Filters with hECE cells were mounted with pH electrodes and shifted to basic salt solution. After 5 min 1.2 mM EGTA plus 1.2 mM CdCl2 (Cd) were added to the luminal and contraluminal solutions from concentrated ×1000 stocks (pH 7.35). Determinations of L-pHo (A) and CL-pHo (B) were described in Materials and Methods. The experiment was repeated twice with similar trends.
