Description
Summary:Using standard hybridoma technology and hierarchical screening, monoclonal antibodies (MAbs) were obtained with specific reactivity against two developmental stages of Globodera pallida. The procedure was based on enzyme-linked immunosorbent assay (ELISA) with homogenates prepared from second-stage juveniles, young adult females, and potato roots. Hybridomas were formed by fusing myelomas with splenocytes derived from mice immunized with either infective juveniles or females of G. pallida. About 600 hybridoma lines were screened from the fusion involving the mouse immunized with juveniles. Two MAbs (LJMab 1 and 2) were identified with high reactivity toward second-stage juveniles but no reactivity with either potato roots or females of G. pallida. A total of 630 cell lines was screened from the corresponding fusion involving the spleen of a mouse receiving immunogens from adult female nematodes. One MAb (LFMAbI) was obtained with the required specificity against only adult female G. pallida. This work extends the application of monoclonal antibodies in nematology from valuable probes for research and species identification to recognition of developmental stages. These specific Mabs have potential value in plant breeding programs for screening for resistant lines unable to support nematode development
