Anion transport in single erythrocyte ghosts measured by fluorescence microphotolysis. 1984

R Peters, and H Passow

Fluorescence microphotolysis was used to measure in single resealed human erythrocyte ghosts the band 3-mediated transport of the fluorescent anion N-(7-nitrobenzofurazan-4-yl)-taurine (NBD-taurine). Transport was reduced to less than 5% of the control by the specific inhibitor 4,4'-diisothiocyanostilbene-2,2'-disulfonate (DIDS). The accuracy of the determination of the rate constant for NBD-taurine influx was approximately +/- 15% as calculated from repetitive measurements in individual ghosts. The sample population distribution of the rate constant was slightly skewed towards values larger than the mean. The rate of NBD-taurine transport showed an optimum near pH 7. The Arrhenius plot was linear in the range from 28.5 degrees C to 51 degrees C with an apparent activation enthalpy of 21.4 kcal/mol.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D007834	Lasers	An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

D005456	Fluorescent Dyes	Chemicals that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags.

D000838	Anions	Negatively charged atoms, radicals or groups of atoms which travel to the anode or positive pole during electrolysis.	Anion
D001457	Anion Exchange Protein 1, Erythrocyte	A major integral transmembrane protein of the ERYTHROCYTE MEMBRANE. It is the anion exchanger responsible for electroneutral transporting in CHLORIDE IONS in exchange of BICARBONATE IONS allowing CO2 uptake and transport from tissues to lungs by the red blood cells. Genetic mutations that result in a loss of the protein function have been associated with type 4 HEREDITARY SPHEROCYTOSIS.
