Figure 1: Schematic diagram of the construction strategy for pMCMV.

(A) Full-length MCMV genome showing positions of restriction sites. (B) PCR-amplifed digestion products that were sequentially inserted into pCB301 to produce pMCMV. Positions of duplicated 2 × 35S promoter, hepatitis delta virus antigenomic ribozyme (HDV_Rz) and NOS terminator in pCB301 are indicated. Transcriptional start site and the HDV_Rz cleavage site are indicated. (C) Organization of MCMV cDNA between the StuI and SmaI sites. Positions of individual MCMV ORFs are shown. The read-through stop codons for p50 or p7 are also indicated.
