FIG. 3.
Anti-MV NP antibody response as measured by enzyme-linked immunosorbent assay in BALB/c mice immunized with 5 μg of pV1J-NP by epidermal gene gun. Sera were collected 3 weeks after immunization. Each pair of bars represents an individual animal. Sera from mice immunized with a control pV1J had means ± standard deviations of 13 ± 45 ng/ml of IgG1 anti-NP antibodies (n = 11) and 83 ± 276 ng/ml of IgG2a anti-NP antibodies (n = 11).
