Characterization of the recombinant RNA packaged in AR–HIV-B. reRNA was isolated from AR–HIV-B, fractionated in a denaturing 1% agarose gel, stained with ethidium bromide, and detected by UV fluorescence. The reRNA was transferred to a membrane and probed with a 32P-labeled oligonucleotide to the 3′ end of the HIV-B sequence. Abbreviations: M, RNA markers; AR, AR–HIV-B reRNA.
