  • Process and agent for detecting antibodies against Treponema pallidum
    Patent number: 6479248
    Abstract: A method and agent for antibodies against Treponema pallidum are provided. The method involves gene-amplifying and cloning a selection of recombinant antigens. The selection of recombinant antigens consists of 17 kD antigen, 47 kD antigen and TmpA. The antigens are expressed in host vector systems, followed by purification. The purified antigens are then bound to a solid phase individually or in combination, and subjected to a reaction with a clinical specimen. The antibodies bound from the clinical specimen by means of an antigen/antibody reaction are determined by means of a detection system wherein the selection of the recombinant antigens for detecting antibodies to Treponema pallidum consists of 17 kD antigen, 47 kD antigen and TmpA.
