Abstract

By using an osmotic stress technique (LeNeveu, D. M., et al. (1977) Biophys. J. 18, 209), we have measured the net repulsive force between egg lecithin bilayers containing various amounts of the charged lipids phosphatidylglycerol and phosphatidylinositol. At bilayer separations greater than about 30 A, the repulsion is dominated by electrostatic forces; its variation with both bilayer separation and charge density is well described qualitatively by simple electrostatic double-layer theory. Quantitative agreement requires, however, that only about 50% of the phosphatidylglycerol polar groups be dissociated. At all charge densities, even for pure phosphatidylglycerol, and at bilayer separations less than about 30 A, the repulsion is dominated not by the electrostatic force but by a strong "hydration force" (LeNeveu, D. M., et al. (1977) Biophys. J. 18, 209). We conclude that the hydration force demands more attention than it has enjoyed hitherto in attempts to understand bilayer membrane interaction and fusion.

  • Hydration repulsion forces between charged lipid bilayers across water have been measured up to similar pressures (10^7 N/m^2).

    “Hydration repulsion forces in a completely different configuration -though one of relevance to systems we describe later in this review -have been measured up to similar pressures (10 7 N/m 2 ) between charged lipid bilayers across water [63].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
