viral proteins reconstituted into dimyristoylphosphatidylcholine liposomes were shown to have retained hemagglutination , low-ph-dependent hemolysis , and neuraminidase activities and were associated with a lipid bilayer in two types of complexes with average lipid to protein mole ratios after sucrose density gradient purification of either 590:1 or 970:1 .
