Preparation of Monospecific Antiserum to Lupin Nodule Glutamate Dehydrogenase

Abstract

Immunization of rabbit, using biochemically homogeneous glutamate dehydrogenase, proved to be unsuitable to produce monospecific antiserum. The presence of traces of contaminating immunogen (undetected by physicochemical methods) induced the production of other antibodies. Procedures for rigorously establishing monospecificity of antisera and a technique for preparation of monospecific antiserum, using immunologically impure antigens, are described.
