Antiretinoblastoma monoclonal antibodies.

Mouse-mouse somatic hybridization techniques were used to produce monoclonal antibodies directed towards antigen expressed on retinoblastoma-derived tissue culture cell lines. Four monoclonal antibodies were produced with varying avidity which were reactive against allogeneic retinoblastoma-associated antigens. Sensitivity and specificity was demonstrated using ELISA and chromium release assays. Immunofluorescent antibody studies suggest that these monoclonal antibodies may be useful diagnostically.
