Coimmunoprecipitation of the ORF9 protein and IE62. (A) Coimmunoprecipitation of the ORF9 protein and IE62 using the monoclonal H6 anti-IE62 antibody. Lane 1, infected cell extract; lane 2, material bound to protein G-Sepharose beads coupled with anti-IE62 antibody; lane 3, beads alone. Upper panel, ORF9 protein; lower panel, IE62. (B) Coimmunoprecipitation of IE62 using polyclonal anti-ORF9 protein antibody. The lane designations are identical to those in panel A.
