Abstract
A composition and method are provided for the making of cholesterol containing phospholipid liposomes such that when dried and then reconstituted, the liposomes retain their structure and size distribution as well as substantially all of the material that was originally encapsulated, and they behave biologically in a normal fashion. The cryoprotective agents are used in the aqueous medium to hydrate the phospholipid(s) and are a combination of at least one sugar and at least one protein, polypeptide, and/or oligopeptide.
