Kaposi's sarcoma-associated herpesvirus ori-Lyt-dependent DNA replication: involvement of host cellular factors.

abstract：:The investigation of papillomavirus chromatin has been hampered by the unavailability of a tissue culture system for vegetative growth of these viruses. We have used, therefore, bovine papillomavirus type 1-transformed hamster embryo fibroblasts containing 200 to 250 episomal genome equivalents per cell as a source of...
