FIG. 2.

Expression of m142 and m143 in transduced and infected cells. (A) Western blot and (B) indirect immunofluorescence analysis of NIH 3T3 cells stably transduced with retroviruses encoding HA-tagged m142 and m143 proteins, respectively. (C) Detection of HA-tagged m142 and m143 proteins expressed by the revertant MCMVs Rm142 and Rm143, respectively, by Western blotting and (D) immunofluorescent staining of infected NIH 3T3 cells. Nuclei were stained with propidium iodide (PI) or DAPI. mock, mock infected.
