A monoclonal antibody to the double-stranded polyribonucleotide complex poly(A) X poly(U)
A monoclonal antibody to the double-stranded polyribonucleotide complex poly(A) . poly(U) was derived from the fusion of spleen cells from immunized DBA/2 mice and the P3 X X63-Ag8 plasma cytoma. Specificity studies using radioimmunoassays showed that the anti-poly(A) . poly(U) does not cross-react with single-stranded polyribonucleotides. RNA X DNA hybrids or DNAs. In addition to RNA duplexes associating adenine and uracil, it recognizes synthetic poly(I) . poly(C) and naturally occurring reovirus RNA. It is thus directed against a conformational epitope with an absolute requirement for two polyribose phosphate chains. However, the antibody does not cross-react with poly(G) . poly(C) and is therefore able to distinguish between RNA double helices.
