    摘要: A new and substantially improved type of lipid vesicle, called stable plurilamellar vesicles (SPLVs), are described, as well as the process for making the same and X-ray diffraction methods for identifying the same. SPLVs are characterized by lipid bilayers enclosing aqueous compartments containing one or more entrapped solutes, the concentration of such solutes in each aqueous compartment being substantially equal to the emunization of solutes used to prepare the SPLVs. The bilayers of SPLVs are substantially non-compressed. SPLVs are stable during storage and can be used in vivo for the sustained release of compounds and in the treatment of disease.

    摘要: An immunoassay utilizing a novel liposome composition in which there is incorporated a stabilizing or destabilizing component and an antigen. The presence of cognate antibodies in test samples is detected by the alteration of the supramolecular structure of the liposomes resulting in changes in stabilization. Destabilization can be detected, and in certain cases, caused by, the addition of magnesium or calcium ions. Increased stabilization can be detected by the polymerization of bilayer components in response to ultraviolet light. Antibody-antigen interactions at the liposome surface mediate the stabilization/destabilization response.
