VOLUME DEPENDENCE OF MEMBRANE ELEVATIONS ON INTACT ERYTHROCYTES IN FREEZE-ETCH ELECTRON MICROSCOPY.

Author(s) : GOEKOOP J. G., SPIES F.

Type of article: Article

Summary

ERYTHROCYTE MEMBRANE ELEVATIONS ARE CAUSED BY THE USE OF A RELATIVELY LOW COOLING RATE IN FREEZE-ETCH ELECTRON MICROSCOPY. THEIR DEPENDENCE ON A VOLUME DECREASE RESULTING FROM OSMOTIC STRESS DURING FREEZING IS SUGGESTED BY THE ABSENCE OF ELEVATIONS ON OPEN GHOSTS. THIS HYPOTHESIS IS CONFIRMED BY AN EXPERIMENT IN WHICH THE VOLUME OF THE ERYTHROCYTE AND THE SALT CONCENTRATION ARE VARIED INDEPENDENTLY.
