As snake venom involves a variety of proteins and enzymes getting administered into the animal, this process can inflict significant harm to the animal, therefore choosing carriers that can deliver the least amount of venom could be a safer option for animal immunization\u0000\u0000\u0000\u0000In this research, nanoliposomes were used to encapsulate venom as a protected cargo for immunization. We used two distinct liposomal formulations to entrap the venom: 1,2-distearoyl-sn-glycero-3-phosphocholine, 1,2-distearoyl-sn-glycero-3-phospho-(1′-rac-glycerol) associated with cholesterol in one formulation and dimethyldioctadecylamonium (Bromide salt) paired with cholesterol in the other.\u0000\u0000\u0000\u0000Liposomal formulations prepared by solvent evaporation method and the venom was encapsulated in liposomes and evaluated for size and zeta potential. Meanwhile, encapsulation efficiency, venom release percentage, and phospholipase activity have all been analyzed.\u0000\u0000\u0000\u0000The findings revealed that dimethyldioctadecylamonium (Bromide salt) combined with cholesterol had the highest encapsulation efficiency. In this formulation, the venom release rate had a steady-state profile. The lack of phospholipase activity in this formulation may be due to a bromide group in the liposomal structure that could be useful for immunization.\u0000\u0000\u0000\u0000Liposomal formulations, which do not have the active site of the snake venom enzymes, could be used for venom encapsulation.\u0000","PeriodicalId":438678,"journal":{"name":"Venoms and Toxins","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131565276","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}
