Mutations in the nsP1 coding sequence of Sindbis virus which restrict viral replication in secondary cultures of chick embryo fibroblasts prepared from aged primary cultures.

Abstract excerpt

SVMPA, a mutant of Sindbis virus (SV), which is able to replicate in Aedes albopictus cells treated with mycophenolic acid (MPA) or ribavirin, also has a host range phenotype. This phenotype is most clearly demonstrated by means of efficiency of plaquing (EOP) assays on secondary chick embryo fibroblasts (CEF) prepared from aged primary CEF. For example, in one experiment in which standard SV (SVSTD) had a...
