ABSTRACT
In order to develop monoclonal antibodies (McAbs) against the gp90 protein of reticuloendotheliosis virus (REV), the His-tagged gp90 protein of REV was used to immunize BALB/c mice. Hybridomas were generated by fusing mouse myeloma cells SP2/0 with the splenocytes from the immunized mice. After screening and 3 rounds of cloning process, 3 hybridomas (3G5-B8, 3G5-A10 and 1G12) that stably secreted McAbs against the REV-gp90 were obtained. The isotypes of the McAbs were determined to be IgG1, IgG1 and IgG2b. The McAbs specifically bound to gp90 in REV-infected DF-1 cells, as demonstrated by Western blotting and indirect immunofluorescence assay. The recognition regions on gp90 that were recognized by 3G5-B8/3G5-A10 and 1G12 were located between amino acids 200 to 245 and 230 to 235, respectively, as demonstrated by Western blotting analysis. These McAbs will be useful in the diagnosis and pathogenesis study of REV.
