Replication of latent Epstein-Barr virus genomes in Raji cells
Abstract
The replication of the 50 to 60 latent, predominantly extrachromosomal, Epstein-Barr virus genomes maintained by the Burkitt-lymphoma-derived Raji cell line was investigated by using a Meselson-Stahl density transfer approach. Samples of DNA isolated from cells cultivated for different periods in bromodeoxyuridine-supplemented medium were fractionated according to density, and the distribution of viral and cellular DNAs among the heavy-, hybrid-, and light-density species was quantitated. The results indicate that the majority of latent Epstein-Barr virus DNA plasmids each replicate once during the cell cycle.
