FIG. 1.

Immunoblots from control, vaccinated, and challenged mice from DNA vaccine trial I. Sera from mice were blotted against M. avium subsp. paratuberculosis proteins from a whole-cell sonicate to assay for reactivity. Lane Ng, no DNA, noninfected; lane Ps, no DNA, infected; lane Gd, microcarrier, infected; lane pV, vector DNA, infected. Clone pool numbers are indicated above the other lanes. The lines above the lane designations cluster the vaccination groups into infected control groups, protected groups, and nonprotected groups (from left to right). The positions of molecular mass standards (in kDa) are indicated on the left.
