Detection of virus-specific RNA in herpes simplex virus type 1-transformed hamster cell lines

In situ hybridization experiments with the use of recombinant herpes simplex virus type 1 DNA as probes have detected virus-specific RNA in herpes simplex virus type 1-transformed Syrian hamster cell lines. The relatively most abundant virus transcripts hybridized to the herpes simplex virus type 1 EcoRI-F fragment at map position 0.32-0.42.
