Abstract

Lipid vesicles, such as those containing inositol hexaphosphate useful for improving the oxygen-release of intact erythrocytes, may be rendered stable to long term storage at temperatures below the freezing point of the encapsulated solution, by rapid freezing at a temperature of from about -196.degree. C. to about -30.degree. C.
