The highest content of the antigen on the membrane surface was observed when using palmitoylized protein and liposomes with egg lecithin, cholesterol and dicethylphosphate in the molar ratio 7:2:1.","PeriodicalId":23403,"journal":{"name":"Ukrainskii biokhimicheskii zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79190557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
