Enhanced SV40-virus replication in Chinese hamster kidney cells pretreated with 5-iodo-2?-deoxyuridine

Abstract
SV40 virion production was enhanced when semipermissive Chinese hamster kidney cells were treated with 5-iodo-2′-deoxyuridine (IUDR), prior to infection either with virus or viral-DNA. Pretreatment did not increase SV40 replication in fully permissive monkey kidney and nonpermissive Syrian hamster or mouse embryo cells.
