title: Production and use of monoclonal antibodies for the detection of apple chlorotic leaf spot virus.
abstract: Stable hybridoma cell lines secreting antibodies specific for the apple chlorotic leaf spot virus (CLSV) were produced by fusing spleen cells of a Biozzi mouse immunized with CLSV P863 strain, with the non-secretory P3 X63 Ag8.653 myeloma cell line. Two hybridoma clones producing monoclonal antibodies of the IgG1 subclass were obtained. These monoclonal antibodies were used for virus detection by enzyme-linked immunosorbent assay (ELISA). In contrast to polyclonal antisera to CLSV, which always contain some antibodies to host components, monoclonal antibodies are highly specific for the virus. It was thus possible to develop a detection assay which is more sensitive and specific than the assays using polyclonal antibodies. Using monoclonal antibodies, it was possible to detect less than 0.1 ng/ml of purified virus. In addition, these two monoclonal antibodies recognize 17 strains or isolates maintained in our laboratory and representing most of the known CLSV strains.
