Figure 4From: UL28 and UL33 homologs of Marek’s disease virus terminase complex involved in the regulation of cleavage and packaging of viral DNA are indispensable for replication in cultured cellsDemonstration of the virus plaques in CEF transfected with DNAs of parental virus, MDV △UL33, MDV △UL33-Re. A Plaque detection by regular light. Letter a represents un-transfected cells; letter b represents DNA of parental virus transfected cells; letter c represents DNA of MDV △UL33 transfected cells; letter d represents DNA of MDV △UL33-Re transfected cells; B IFA analysis of MDV plaques in CEF. Images of e, f, g, h represent the same cell as images a, b, c, d, but stained with MDV specific gB monoclonal antibody and examined by fluorescent microscopy.Back to article page
