Preparation of immunoliposomes encapsulating alkaline phosphatase / 重庆医科大学学报

ABSTRACT

Objective:To prepare immunoliposomes encapsulating alkaline phosphatase and to evaluate the methods.Methods:The liposomes containing alkaline phosphatase were prepared by reverse phase evaporation or film dispersion.Liposomes and rabbit anti-human IgG were conjugated by glutaraldhyde or deriving antibody.Not only did the liposomes encapsulate alkaline phosphatase but also they had immune activity.All methods were analyzed and compared.Results:Many liposomes prepared by reverse phase evaporation had perfect shape and high bioactivity of alkaline phosphatase.The glutaraldhyde method conjugating antibody was convenient,efficient and practical.Conclusion:Immunoliposomes with bioactivity of enzyme and antibody are prepared through reasonable methods.
