ABSTRACT
<p><b>OBJECTIVE</b>To express and purify HBoV VP2 protein, and the monoclonal antibody against HBoV VP2 protein was prepared with hybridoma technique.</p><p><b>METHODS</b>The HBoV VP2 cloned into vector pET-30a was expressed in E. coil. After purified by immobilized metal affinity chromatography, the BALB/c mouse was immunized with purified protein as antigen. The positive hybridoma cells were screened with hybridoma technique and ELISA assay. Isotype and titer of the monoclonal antibody were detected.</p><p><b>RESULTS</b>The recombinant HBoV VP2 protein was expressed and purified, and then the monoclonal antibody was obtained with hybridoma technique. The titer of the IgG monoclonal antibody was up to 1:4 x 10(5).</p><p><b>CONCLUSION</b>Monoclonal antibody against recombinant HBoV VP2 protein was prepared and the antibody titer was high. This work may provide a new method in rapid diagnosis and study of HBoV.</p>
