    Abstract:
    Monoclonal antibodies (McAb) of hybridomas derived from the fusing of the mouse splenocytes immunized by TuMV with BALB/c mouse myeloma cells (SP2/0-Ag14). Five kinds of hybridoma cell line were produced by indirect-ELISA screening and cloning three times with limiting dilution. Four kinds of hybridoma produced antibodies respectively reactive to TuMV C1, C3, C4 and C5. One kind was reactive to all five strains of TuMV. In indirect-ELISA and sandwich-ELISA tests, TuMV specific monoclonal antibodies did not react with CaMV, CMV, TMV, PVX, and PVY. Antibody titers of ascitic fluids were about 1:256,000 to 2,048,000 in indirect-ELISA. The biological, physical, and chemical properties of the hybridoma cell lines and McAb were identified. The identification of TuMV strains, the specificity and stability of McAb, the coat proteins, and the antigenic site of TuMV were discussed and analyzed with SDS-PAGE and western-blotting.
