Abstract: Polyclonal antibodies to recombinant Potato virus X (PVX) coat protein (PVX-CP) were developed and their effectiveness determined in different ELISA protocols. The PVX-CP gene was amplified by reverse transcription-polymerase chain reaction, cloned and expressed in Escherichia coli. For immunization, the CP fractions from bacterial lysate were purified either by simple fractionation or by excision from sodium dodecyl sulphate gels. The PVX-CP was injected into rabbits for antibody production. The PVX-CP antibodies reacted in an indirect plate trapped antigen enzyme-linked immunosorbent assay and immunoblot assay and were useful for the detection of a broad spectrum of isolates of PVX.
