1. Intracellular pH (pHi) and calcium (Cai2+) were studied in freely migrating neural crest cells and in closely packed non-migrating cells derived from avian neural tubes in vitro, using the fluorescent dyes 2,3-dicyanohydroquinone (DCH) and Indo-1 to measure pHi and

In this study we describe a method to measure intracellular pH in cultured human keratinocytes using flow cytometry. Keratinocytes pose a technical problem because the population is heterogeneous with respect to size and metabolic activity (nonspecific esterase activity), resulting in

The new intracellular pH (pH(i)) dye carboxy-seminaphthorhodafluor (SNARF-1) was compared to the established dye 2,3-dicyanohydroquinone (DCH) using flow cytometry. Both dyes give high-resolution pH(i) measurements. SNARF-1 remains trapped within cells much longer than DCH, so that pH(i) can be monitored

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
