Radioimmunotherapy with 131I-labeled monoclonal immunoglobulins was studied using the Rauscher murine erythroleukemia. Tumor-specific monoclonal antibody, nonrelevant monoclonal antibody, F(ab')2 fragments, polyclonal gamma-globulin, and serum albumin were used as carriers of 131I. Therapeutic effects as measured by the reduction in splenomegaly were seen with all the radiolabeled proteins test...

Monoclonal antibodies (MAbs) are invaluable molecules which have several advantages over polyclonal immunoglobulins (Igs) including consistency and higher specificity and hence can be used in biological researches, diagnosis and treatment of diseases. The present study was conducted to produce monoclonal antibody against chicken IgG.TheIgG molecules were purified from chicken serum and used as ...

A monoclonal antibody to the lipopolysaccharide of Moraxella bovis is described. In an indirect fluorescent-antibody test, this monoclonal antibody reacted with 39 of 39 strains of M. bovis tested and did not react with 26 nonfermenting gram-negative coccobacilli other than M. bovis. When used in an indirect fluorescent-antibody test, it proved useful for rapid and easy identification of M. bovis.
