The B95-8 isolate of Epstein-Barr virus arose from an isolate with a standard genome.

RESUMO

Blot hybridization studies revealed that the deletion which characterizes the DNA from the B95-8 strain of Epstein-Barr virus was not present in the virus from which the B95-8 strain was derived (883L). The deletion event must have occurred during establishment of the B95-8 cell line or very soon afterward, since the deletion was present in Epstein-Barr virus DNA from a cell line established with B95-8 virus soon after it became available. The presence of the deletion correlates with decreased expression of the gp220 viral envelope glycoprotein.
