Abstract
Ribonucleic acid (RNA) can act as a hapten in the direct immunization of animals. For antigen synthesis, 65 mg of viroid RNA were obtained by in vitro transcription of the recombinant DNA. We received a reasonable immune response in mice and rabbits with synthesized conjugate viroid RNA-lysozyme. Analyses of polyclonal mouse and rabbit antisera as well as estimates of antibody specificity were performed by dot-Enzyme Linked Immunosorbent Assay (ELISA), sandwich ELISA, and northern immunoblotting. Antiserum obtained showed strong cross-reactions with cellular RNA. The viroid polyclonal antibody cross-reactions with cellular RNAs were depleted via titration antibodies by the plant cellular or commercial yeast RNA. We successfully used antibodies against the viroid RNA-lysozyme antigen to detect the wild-type potato viroid and diagnose potato viroid infection. We presume that intrinsic cross-reactions of RNA antibodies are potentially dangerous after nucleic acid vaccination. Research into the specificity of antibodies against viral RNAs is underway.
