[Electroimmunodiffusion with Reiter treponema antigen shows serum immunoglobulin isolated from subjects with secondary syphilis].
The results of electroimmunodiffusion investigations with Reiter treponema antigen and syphilitic subject sera are presented. Counter-immunoelectrophoresis, rocked electrophoresis and crossed-electrophoresis studies have been performed. The test positivity is shown by the appearance of one ore two precipitates. No aspecificities were remarked with the latter two techniques: particular attention was devoted to the preparation of the treponema antigen in the attempt to eliminate the aspecificity which, sometimes, occurs above all with counter immuno-electrophoresis. Immuno-sorbents were also prepared to isolate IgG involved in this reaction: the latter turned out to be slow-migration IgG. Agarose-agar electroimmunoprecipitation between treponema antigens and sera of syphilitic subjects supplies possibilities for diagnosis and research in the field of treponema antigens and in the formation of antibodies in the syphilitic disease.
