Abstract
Antisera prepared in rabbits against frog ovi-ductal homogenate produce a minimum of 6-9 precipitation bands in agar-gel diffusion plates. Individual bands were isolated from several plates and injected into rabbits to produce antibodies specific to the antigen represented in the precipitate. Bands formed with antigen excess or antibody excess were effective in eliciting an immune response against the antigen. Antibodies produced against the [gamma]-globulin portion of the precipitate were detected in the serum of 1/2 the rabbits injected. Rats injected with the above isolated precipitates failed to produce antisera specific to individual rabbit antibodies. Agar-gel diffusion and immunoelectrophoresis showed that isolated precipitin bands may be used for the production of specific antisera against a single antigen in a complex mixture.
