Membrane potential and Donnan potential

Biophysical Chemistry, 1988
The Nernst-Planck-Poisson equations for the potential profile across a membrane are exactly solved without recourse to the assumption of constant field within the membrane. It is assumed that the membrane core of thickness dc is covered by a surface layer of thickness ds in which the membrane-fixed charges are distributed at a uniform density N.

Membrane potentials for keratin

Journal of Colloid Science, 1947
Abstract Measurements of the membrane potentials of keratin membranes have been made using KCl and NaCl and the results show how the selectivity of the membranes can be altered by soaking in suitable buffer solutions. The results support Toerell's theory of membrane behavior in neutral salts, and some membrane potential measurements using HCl ...

Membrane potential of bipolar membranes

Journal of Electroanalytical Chemistry, 1996
Abstract The membrane potential of a bipolar membrane composed of a cation-exchange layer in series with an anion-exchange layer is analyzed theoretically and experimentally. The theoretical approach is based on an extension of the Nernst-Planck equations of monopolar charged membranes to the case of the two ion-exchange layers in series and the ...

DC Potentials of the Membranous Labyrinth

American Journal of Physiology-Legacy Content, 1958
The endolymphatic DC potentials were measured in the utricle, saccule and cochlear duct of the membranous labyrinth of the guinea pig and compared with potassium analyses of the endolymph. The average utricular potential was found to be +4 mv, the saccular potential +1 mv, and the cochlear potential +65 mv.

Recognition of substrates by membrane potential of immobilized enzyme membranes: membrane potential theory

Journal of the Chemical Society, Faraday Transactions, 1991
The shifts in membrane potential, caused by the injection of D-glucose into a permeation cell, were obtained theoretically from membrane potential theory and compared to experimental data measured for immobilized (entrapped) glucose oxidase membrane and its lamellar enzyme membranes.

Streaming Potentials in a Biological Membrane

Nature, 1964
STREAMING potentials, the converse of electro-osmosis and one of the four classical electrokinetic phenomena, are the electrical potential differences frequently observed across charged artificial membranes through which water is being forced. They arise from the fact that if the membrane matrix bears, say, negative fixed charges, the aqueous channels ...

Relationship of epithelial membrane potentials to corneal potential

Experimental Eye Research, 1973
Abstract The rabbit corneal potential arises as the sum of three steps across the epithelium. These occur across the squamous cell outer membrane, at the transition region between wing and basal cells, and across the basal cell inner membrane. Variations in corneal potential are inversely proportional to outer membrane potential.

Membrane potentials inStentor coeruleus

Protoplasma, 1971
The membrane potential ofStentor coeruleus was measured by means of glass microelectrodes. The tips of the electrodes had a diameter of 2 μ, and were filled with 0.1 M KCl. The maximum value of the potential is −30.8±8.6 mV and is reached within 600–800 msec after electrode insertion; the potential then decreases to a negative value of a few mV within ...
