ORF9 and IE62 are coprecipitated by anti-β-tubulin antibodies. (A) Immunoblot analysis of coimmunoprecipitation experiments using anti-β-tubulin antibodies. Lane 1, input from whole-cell extract; lane 2, eluate from antibody-bound beads; lane 3, eluate from beads alone without antibody. Arrows indicate the positions of the ORF9 protein, IE62, gE, and β-tubulin. (B) Results of control experiments using monoclonal IgG directed against the Xpress peptide and analyzed for the presence of the ORF9 protein and IE62. The lane designations are as described for panel A.
