title: [Study on monoclonal antibodies against porcine serum E receptor].
abstract: Three hybridoma cell lines producing monoclonal antibodies (McAbs) against porcine serum E receptor (PSER) were established by fusing mouse myeloma SP2/o cells with spleen cells of BALB/c mouse immunized with PSER. The ascites McAbs were purified by ammonium sulfate precipitation and DEAE-cellulose chromatography. The McAbs were found to belong to the IgG1 and IgG2b subclasses, respectively. These McAbs inhibited reverse E-rosette formation and enhanced or depressed lymphocyte proliferation induced by PHA or ConA. The specificity of these McAbs was proved by immuno-dot blot and Western blot assay. The potential application of these McAbs in the study of structure and biological function of the E-receptor is discussed.
