the specificity of the two antisera evaluated in this study was verified by ( i ) immunoblots in which reactivity against the 78- or 40-kda omp was present in postimmunization but not preimmunization serum and ( ii ) immunoblots in which affinity-purified , surface-reactive antibodies in each antisera were used , which demonstrated that essentially only antibody to the 78- or 40-kda omp was reactive with the surface of h. somnus .
