A large quantity of polyclonal anti-ovalbumin antibodies was obtained from mice by a simple modification of the method described by Kurpisz et al. (1988). In addition, the cells from ascitic fluid were used to produce monoclonal antibodies. Egg ovalbumin hyperimmunized BALB/c mice were injected successively with pristane, antigen and a non-antibody secreting myeloma cell line: the production of ascitic fluid containing antiovalbumin antibody activity was observed after 10-25 days. Cells from ascitic fluid were harvested, washed and fused together with polyethylene glycol to produce monoclonal antibodies. Two fusions were performed and a large number of monoclonal anti-ovalbumin antibodies was obtained. This method is simple, reproducible, allows many fusions to be obtained from one mouse, and allows the use of ascitic B cells rather than the more, frequently used splenic B cells.
