چکیده انگلیسی
In this paper we report our efforts to enhance the immunogenicity of Pfs28, a transmission blocking vaccine candidate of Plasmodium falciparum, using a strategy of chemical conjugation. With an improved procedure, Pfs28 was covalently coupled to the mutant and non-toxic ExoProtein A of Pseudomonas aeruginosa by the reaction between thiolated antigen and maleimide modified carrier protein. The optimized process resulted in a higher antigen-carrier conjugation ratio, and the conjugation product could be purified using single-step size-exclusion chromatography. A significant increase in immunogenicity measured by ELISA was observed in mice immunized with conjugated Pfs28 as compared to unconjugated Pfs28.
