IgG sub-classes of specific antibodies in mice immunized with recombinant B. bovis merozoite antigens. Mice were immunized as described in Fig. 3. Antibody titers of each IgG subclass (IgG1, IgG2b, IgG2c) to each B. bovis merozoite antigen were determined by using a pool of sera from each mouse group. a rMSA-2a1.
b rMSA-2b. c rMSA-2c. These data represent one of two independent experiments
