Abstract:
In this study, we developed a simple and sensitive assay in mice for a challenge experiment by using a recombinant vaccinia virus dual-expressing antigen (HIV Env gp160) and firefly luciferase. This assay can detect the vaccine effect at real-time in vivo by using a small amount of mouse serum. The luciferase activity in mouse serum was in agreement with the viral titer in the ovary. This assay would be applicable as a challenge model for infectious diseases.
