Antibody titers were determined in mice (n = 4) two weeks after the last immunization. The 96-well plates were coated with SARS-NC protein and mouse sera were serially diluted in wells for the endpoint titration of anti-NC antibody. Results are shown as mean concentration ± S.D. The symbol * indicates a significant difference (P = 0.01–000.1) compared with all other groups. The symbol †indicates a significant difference (P ≤ 0.001) when compared to animals immunized with DNA+XIAP and DNA-NC alone.
