Immunodiagnostic test for syphilis and other treponemal infections

摘要

A component for the rapid detection of anti-Treponema pallidum antibodies adapted for use as a selective foundation material in standard immunoassays is provided. The component comprises a quantity of fibronectin insolubilized to a solid matrix. The fibronectin component provides a foundation material for the selective binding of antigenic outer membrane proteins extracted from Treponema pallidum. Incorporation of the insolubilized fibronectin component bound to the antigenic outer membrane proteins extracted from Treponema pallidum into a standard immunoassay test pack provides an immunological assay for the presence of respective complementary anti-Treponema pallidum antibody in a biological sample.
