Membrane potential of bipolar membranes
Journal of Electroanalytical Chemistry, 1996Abstract 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 ...

Membrane potentials for keratin
Journal of Colloid Science, 1947Abstract 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 potentials inStentor coeruleus
Protoplasma, 1971The 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 ...

Membrane potential, surface potential and ionic permeability
Physics Letters A, 1979To clarify contributions to cellular transmembrane potential concentration potentials of phospholipid bilayer membranes and surface potentials of phospholipid monolayers were measured with respect to salt concentrations and various surface charge densities.

There are two populations of scientists who have, respectively, employed two different classes of voltage-sensitive dyes. The larger group, of cell biologists, has primarily used slow (response time > s) redistribution dyes for measurements of membrane potential changes in suspensions of cells or energytransducing organelles (Freedman and Laris, 1981 ...
