FIG. 3.

Transfer of hygromycin phosphotransferase DNA (top) and viral DNA (bottom) by infection of EBV-negative B-lymphoma cells (BJAB-ZE1) with EBV-, rhesus monkey LCV-, or baboon LCV-enveloped amplicons. Genomic DNAs from hygromycin-resistant BAJB-ZE1 clones exposed to EBV-, rhesus monkey LCV-, and baboon LCV-enveloped amplicons were hybridized with a radiolabelled hygromycin phosphotransferase DNA at high stringency (top) or an EBV BamHI W DNA probe at lower stringency (bottom). Uninfected BJAB-ZE1 cells and EBV-, rhesus monkey LCV-, and baboon LCV-infected cells (B95-8, LCL8664, and S594, respectively) were used as controls. Molecular size markers (kilobases) are shown at right.
