【Abstract】 Objective To explore the recombinant protein expression status in muscle tissue of mice vaccinated by DNA vaccine of circumsporozoite protein (CSP) of Plasmodium falciparum FCC 1/HN strain. Methods The recombinant pBK/CSP was injected into BALB/c mice by intramuscular route, with pretreatment of the muscle tissue of the injected sites by bupivacaine hydrochloride, and the expression product of DNA vaccine was detected with indirect immunohistochemistry assay after 4 weeks and 8 weeks immunization. Results The specific positive reaction of the indirect immunohistochemistry assay were observed in muscle tissue and its adjacent connective tissue in immune group.(For Fig. 1-4, to see back cover) Conclusion After vaccinating BALB/c mice with malaria DNA vaccine by injection muscle directly, it is obvious that the recombinant protein CSP could be expressed in the muscle tissue and connective tissue.更多还原
