Phase separation in frozen erythrocyte membrane preparations

Abstract
The reversible formation of a lipid-like phase in frozen preparations of erythrocyte membranes has been studied by X-ray diffraction and by electron microscopy of freeze-fracture replicas. The observations provide strong evidence for lateral migration or displacement at specific temperatures of intra-membrane particles. This creates large areas of particle-free membranes which fracture preferentially so as to dominate the freeze-fracture image.
