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

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 use of 2,3-dicyanohydroquinone (DCHQ) as an emission ratiometric probe of pH in vitro and in fibroblast cells was evaluated using two-photon excitation fluorescence microscopy (TPEFM). In addition, methods for spectrally calibrating the Zeiss LSM510 META spectroscopy system for TPEFM

1. Measurements of intracellular pH (pHi) have been made using the fluorescent dye dicyano-hydroquinone (DCH) in somites isolated from 2-day-old chick embryos. Measurements of pHi, from freshly dissected somites, gave values of 7.18 +/- 0.02 (mean +/- S.D., n =
