Northern blot analysis of rRVs. BSR cells were infected with rRV or
rRV-VSV-G (moi of 1), and total RNA was isolated 24 h later. RNA
was separated by electrophoresis and transferred to a nylon membrane
that was hybridized with a probe specific for RV-N (A),
VSV-G (B), or a cDNA fragment spanning the entire RV-ψ
and a portion of the RV-L gene (ψ + L) (C). G/L
= RV G + L bicistronic RNA, L = RV L, G = glycoprotein,
N = RV-N.
