title: Serotype specificity of monoclonal antibodies to cucumber mosaic virus.
abstract: Ten monoclonal antibodies (McAbs) against cucumber mosaic virus (CMV) have been raised from fusion experiments performed after immunizing mice with different CMV antigens. Their reactivities with members of the three CMV serotypes, CMV-DTL, CMV-ToRS, and CMV-Co were tested in a double antibody sandwich format of enzyme immunosorbent assay (ELISA). Several of the McAbs were specific for different members of the CMV-DTL and CMV-ToRS groups while two allowed the detection of CMV-Co. By using a mixture of two McAbs, any member of the three major CMV serotypes could be detected in infected plant sap. One of the antibodies made it possible to discriminate between subunits and whole virions of CMV-D when it was used in ELISA simultaneously as coating antibody and as biotin-conjugate. McAbs were shown to be useful for quantifying the amount of CMV present in plant sap.
