Quantitative Analysis of Membrane Potentials
2009The changes that occur in electrochemical gradients across biological membranes provide us with invaluable information on physiological responses, pathophysiological processes and drug actions/toxicity. This chapter aims to provide researchers with sufficient information to carry out a quantitative assessment of mitochondrial energetics at a single ...

Membrane potentials of thin nitrocellulose membranes
Journal of Applied Polymer Science, 1967AbstractThe membrane potentials of thin (300–1300 A.) nitrocellulose (Parlodion) membranes have been investigated. Measurements were made in a Lucite cell by use of calomel electrodes with 0.05N KCl and 0.1N KCl. Variables having an influence on membrane structure, such as solvent polarity, temperature, and thickness, have been studied in relation to ...

Equations for the membrane potential
Biophysics, 2009The problem of an electric signal propagating over a thin layer modeling the cell membrane is considered in the electrostatic approximation. At both sides of the membrane there are bulk conductors with different properties. Various types of boundary conditions are examined.

1991
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 ...

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 ...

Generation of the Membrane Potential
2003Knowledge of the existence of bioelectric potentials must certainly go back to the first unfortunate encounters that people had with electric fish, but an understanding of the origin of these potentials awaited the advances in physical chemistry that occurred near the end of the 19th century.
