Immunoproteomic Approach for Screening Vaccine Candidates from Bacterial Outer Membrane Proteins

Outer membrane proteins (OMPs) are unique to Gram-negative bacteria and have been revealed as potential vaccine candidates for conferring protection against infections in recent years. Immunoproteomics is a powerful technique that is ideally suited to screen and identify potential vaccine candidates. This chapter presents a brief outline of the screening of immunogenic OMPs from Vibrio parahaemolyticus by an immunoproteomic strategy that was based on two-dimensional electrophoresis (2-DE) and immunoblotting. The protective efficacy provided by the immunogenic OMP Vp0802 determined by active protection experiment assays is also presented in brief.
