Abstract
Gastric cancer is one of the most common malignant tumors in China. This paper focuses on the development of a DNA vaccine containing four mimotopes of MG7Ag for gastric cancer (multi-epitope vaccine). By inoculating BALB/c mice, the vaccine was characterized and compared with the similar vaccine containing only one mimotope (mono-epitope vaccine) and other controls. Cellular ELISA indicated that serum titer of antibody against MG7Ag was significantly higher in mice immunized with the multi-epitope vaccine than that in the group immunized with the mono-epitope vaccine (0.8627 vs 0.6754, P
