Abstract

SUMMARYThe frequency of particles on the membrane fracture faces of freeze‐etched human erythrocytes was measured, and the effect of fixation procedures on the particle frequencies was studied. Fresh blood, buffer washed cells and cells fixed in one of the following ways were examined: glutaraldehyde, glutaraldehyde followed by osmium tetroxide, osmium tetroxide alone. Quantitative analyses showed that some treatments produced a significant reduction in the number of particles on the fracture faces as compared with the fresh cells. After both osmium tetroxide fixations, the loss of particles was greater from the outer fracture face (OFF) than the inner fracture face (IFF), whilst after the other treatments approximately the same number of particles were lost from both fracture faces. The results are discussed with respect to some current concepts of the molecular architecture of the erythrocyte membrane and the action of fixatives. The reduction of particle frequencies is thought to be due to both leaching of membrane proteins, and deviations of the usual fracture plane within the membrane. Glutaraldehyde alone was shown to have less effect on particle frequency than the other fixatives and it is therefore a suitable fixative for the preparation of freeze‐etch specimens.
