title: Synthesis and protective effects of poly-8-bromoriboadenylic acid: poly ribouridylic acid hybrid against Wesselsbron virus in chick embryos.
abstract: Poly-8-bromoriboadenylic acid was synthesized by the bromination of adenosine-5'-monophosphate to yield 8-bromoadenosine-5'-monophosphate which on conversion to the 5'-diphosphate form was polymerized by polynucleotide phosphorylase (PNPase). The polymer formed a 1:1 hybrid with polyribouridylic acid and the hybrid was found to protect chick embryos against Wesselsbron virus (H10964).
