We have developed new methodology for measuring intracellular pH (pHi) in cultured cell monolayers and epithelia by analyzing the emission spectra of the trapped fluorescent pH probe, 1,4-dihydroxyphthalonitrile (1,4-DHPN). This compound is unique since both its acid and base forms

The present study was carried out to test directly whether isolated perfused rabbit cortical collecting ducts (CCDs) spontaneously generate a luminal disequilibrium pH. We determined disequilibrium pH as the difference between 1) the actual luminal pH measured by perfusing the
