Figure 1

This figure shows serum IgG isotype antibody responses in mice vaccinated with BM5 by intramuscular (IM) N = 7 and Gene Gun (GG), N = 8 immunization. Antigen-specific ELISAs were performed with sera collected 8 wk after the first immunization. A: IgG1 and IgG2a results shown are mean OD + SE for IM and GG mice; B: IgG1 to IgG2a ratios are shown for mice immunized with BM5 by IM and GG routes. Values shown are mean PD +SE. The ratios in the two groups were significantly different (p < 0.05).
