title: EBV-based plasmid DNA rearrangements after transfection of eukaryotic cells.
abstract: The cDNA encoding influenza virus (A/Udorn/307/72 strain) M2 protein was subcloned into the EBV-based vector pREP9. Three continuous kidney cellular lines of different origin were transfected with recombinant plasmid pREP9-M2. One and 5 months after transfection plasmid DNA rearrangements were detected by means of restriction analysis of recovered plasmids and their hybridization with an influenza-virus-specific radioactive probe. Deletions were the most frequent type of pREP9-M2 mutations. PCR with primers corresponding to cellular genome and plasmid DNA followed by Southern blot analysis with the [(32)P]-labeled M2-fragment allowed host DNA rearrangements to be revealed in transfected cells.
