Counterimmunoelectrophoresis of Reiter Treponeme Axial filaments as a diagnostic test for syphilis. 1978

E E Nell, and P H Hardy

Purified axial filaments from the cultivable Reiter treponeme, previously shown to share an antigenic component with pathogenic Treponemia pallidum, were evaluated as antigen in a diagnostic test for syphilis. Antibody to the filaments was revealed by counterimmunoelectrophoresis. Conditions that produced optimal results in the test were established. A total of 343 sera from normal individuals, biological false-positive reactors, and from patients in the different stages of syphilis were subjected to the test. The results indicate the test to be sensitive and highly specific for detecting treponemal antibodies in human syphilis.

UI	MeSH Term	Description	Entries
D007122	Immunoelectrophoresis	A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D003378	Counterimmunoelectrophoresis	Immunoelectrophoresis in which immunoprecipitation occurs when antigen at the cathode is caused to migrate in an electric field through a suitable medium of diffusion against a stream of antibody migrating from the anode as a result of endosmotic flow.
