Expression and purification of CPV-VP2 proteins.

<p>Protein detection using SDS-PAGE (<b>a</b>): lane 1, His-Sumo-VP2 (85 kDa); lane 2, VP2 protein (65 kDa). Identification of proteins using Western blot (<b>b</b>): lane 1, His-Sumo-VP2; lane 2, VP2 protein. Mouse anti-CPV monoclonal antibody was used as the primary antibody (1:1000).
