Southern analysis of recombinant VZVs. (A) Ethidium
bromide-stained gel and Southern analysis of EcoRV-digested
DNA prepared from Vero cells infected with either Oka-ATCC, Oka-R, or
the three recombinant viruses Oka-gB2, Oka-gB3, and Oka-Δ4-3.
Positions of molecular weight markers are shown in kilobases at the
left. (B) Diagram depicting the ORF S/L region from the Oka-ATCC,
Oka-Δ4-3, Oka-gB2, and Oka-gB3 viruses. Oka-ATCC is depicted on the
top line, and the 1.2-kbp XhoI-to-PmeI probe is
indicated. OkaΔ4 has a deletion of 400 nt between the
ApaLI and BspEI sites (▵); and the gB mutants
have a 60-nt CMV gB sequence
() containing a novel
EcoRV site replacing the 120 bp between the EcoRI
and BspEI sites of Oka. Images of the autoradiograms and
stained gels were generated as for Fig. 3.
