Application

An uncharged, nonfluorescent molecule that is useful for noninvasive bulk loading of cell suspension because it is capable of permeating the cell membrane. Cellular nonspecific esterases cleave its lipophilic blocking groups, resulting in a charged, fluorescent form of the molecule. Compared to the parent compound, this charged derivative leaks out of the cell at a much slower rate. Utilized for pH measurements in perfused tissues, intercellular spaces, mammalian cells, plant cells, bacteria, and yeast. Also, employed to investigate in assays for cellular functional properties such as adhesion, multi-drug resistance, viability and cytotoxicity, apoptosis and chemotaxis.
Cell-permeable ester of BCECF that, on hydrolysis by cytosolic esterases, yields the intracellularly trapped pH-indicator BCECF. Allows simultaneous recording of cell volume changes and intracellular pH in single osteosarcoma cells.

We have tested the efficacy of fluorescent probes for the measurement of intracellular pH in Saccharomyces cerevisiae. Of the compounds tested (fluorescein, carboxyseminaphthorhodafluor-1 (C.SNARF-1) and 2',7'bis(carboxyethyl)-5(6')-carboxyfluorescein), C.SNARF-1 was found to be the most useful indicator of internal pH.

The effects of arachidonic acid and thrombin on calcium movements have been studied in fura-2-loaded platelets by a procedure which allows simultaneous monitoring of the uptake of manganese, a calcium surrogate for Ca2+ channels, and the release of Ca2+ from

The strictly aerobic, polyphosphate-accumulating Acinetobacter johnsonii strain 210A degrades its polyphosphate when oxidative phosphorylation is impaired. The endproducts of this degradation, divalent metal ions and inorganic phosphate, are excreted as a neutral metal-phosphate (MeHPO4) chelate via the electrogenic MeHPO4/H+ symport

The lateral intercellular spaces (LIS) of reabsorptive epithelia are the site of the proposed local osmotic gradient responsible for transepithelial transport. We developed techniques for loading the LIS of living cultured renal cells (MDCK and LLC-PK1) with the fluorescent dye

Intracellular pH (pHi) has been measured in intact, perfused rat mandibular salivary glands loaded with the fluorescent pH indicator BCECF [2',7'-bis(2-carboxyethyl)-5(6)- carboxyfluorescein]. Glands mounted in the cuvette of a conventional bench-top spectro-fluorometer were perfused for 5 min with the acetoxymethyl
