The iDart™ Lyme IgM ImmunoBlot tests are line immunoblot assays. Antigenic proteins specific for Borrelia species that cause Lyme Disease are produced by recombinant DNA technology in Escherichia coli. The purified proteins are then applied as discrete lines on a nitrocellulose membrane along with two control proteins. The iDart™ Lyme IgM ImmunoBlot Kit contains IgM ImmunoBlot strips and the proteins are applied in the following order: C1 (IgG/IgM – conjugate control), C2 (Protein L – calibrator/serum control), P93, P41 (2 antigen bands), P39 (2 antigen bands), P23 (9 antigen bands), P31 (9 antigen bands), P34, C10 and LSA (a chimeric VlsE peptide termed the Lyme Screen Antigen).

The Access Syphilis assay is a paramagnetic particle, chemiluminescent immunoassay for the qualitative detection of total antibodies to Treponema pallidum in human serum and plasma using the Access lmmunoassay Systems. It is intended to be used as an aid in the diagnosis of syphilis or in conjunction with a nontreponemal laboratory test and clinical findings to aid in the diagnosis of syphilis infection. The Access Syphilis assay is not intended for blood and tissue donor screening.

The Access Syphilis assay is a two-step enzyme immunoassay. A sample is added to a reaction vessel with buffer, paramagnetic particles coated with recombinant Treponema pallidum antigens Tp17 and Tp47, and Tp47, and biotinylated Treponema Tp17 & Tp47 antigens. After incubation in a reaction vessel, materials bound to the solid phase are held in a magnetic field while unbound materials are washed away. Alkaline phosphatase conjugates are added, and the conjugates bind to the immunoglobulin captured on the particles. A chemilyminescent substrate is added to the vessel and light generated by the reaction is measured with a luminometer. The light production is proportional to the amount of Treponema pallidum antibodies in the sample. The light quantity measured for a sample allows a determination of the presence of the analyte by comparison with a cut-off value defined during the assay calibration on the instrument. The Access Syphilis reagents are provided in liquid ready-to-use format designed for optimal performance on the Beckman Coulter Access Immunoassay Systems. Each reagent kit contains two reagent packs.

For the qualitative determination of total (IgG and IgM) antibodies to Treponema pallidum (TP) specific antigens in human serum and plasma using the VITROS 5600 Integrated System. The presence of antibodies to Treponema pallidum (TP) specific antigens, in conjunction with non-treponemal laboratory tests and clinical findings may aid in the diagnosis of syphilis infection. The VITROS Syphilis test is not intended for blood and tissue donor screening.

The VITROS Immunodiagnostic Products Syphilis test is performed using the VITROS Immunodiagnostic Products Syphilis Reagent Pack and VITROS Immunodiagnostic Products Syphilis Calibrator on the VITROS 5600 Integrated System. An immunometric technique is used; this involves a two-stage reaction. In the first stage antibodies to Syphilis TP specific antigens present in the sample bind with biotinylated recombinant Syphilis TP antigens immobilized on streptavidin coated wells. Unbound sample is removed by washing. In the second stage conjugate reagent containing horseradish peroxidase (HRP)-labeled recombinant Syphilis TP antigens is added. The conjugate binds specifically to any antibody to Syphilis TP specific antigens captured on the well in the first stage. Unbound conjugate is removed by washing. The bound HRP conjugate is measured by a luminescent reaction. A reagent containing luminogenic substrates (a luminol derivative and a peracid salt) and an electron transfer agent is added to the wells. The HRP in the bound conjugate catalyzes the oxidation of the luminol derivative, producing light. The electron transfer agent (a substituted acetanilide) increases the level of light produced and prolongs its emission. The light signals are read by the system.

Immunoassay for the in vitro qualitative detection of total antibodies (IgG and IgM) to Treponema pallidum in human serum and plasma. The test is intended as an aid in the diagnosis of syphilis infection in conjunction with clinical signs and symptoms. The Elecsys Syphilis immunoasay is not in screening blood or tissue donors. The effectiveness of this assay in testing blood or tissue donors has not been established. The electrochemiluminescence immunoassay "ECLIA" is intended for use on cobas e immunoassay analyzers.

The Elecsys Syphilis immunoassay is a fully automated, qualitative assay that uses a double antigen sandwich format for the detection of IgM and IgG antibodies to T. pallidum. Recombinant T. pallidum antigens labeled with either biotin or a ruthenium complex bind to T. pallidum-specific IgG or IgM to form a double antigen sandwich complex. The sandwich complex binds to streptavidin-coated microparticles which can be immobilized magnetically to the surface of an electrode. Unbound substances are removed during a wash step using ProCell. A chemiluminescent substrate is then added to the reaction tube. Application of a voltage to the electrode induces a chemiluminescent emission which is measured by a photomultiplier. The presence or absence of anti-TP antibodies in the specimen is determined by comparing the chemiluminescent signal in the reaction to the cutoff index (COI) determined from an active calibration. The strength of the signal generated is proportional to the amount of bound conjugate and thus the amount of anti-T. pallidum antibodies present in the specimen. If the chemiluminescent signal in the reaction is greater than or equal to the cutoff signal, the specimen is considered reactive for anti-TP antibodies. If the chemiluminescent signal is below the cutoff signal, the specimen is considered nonreactive for the anti-TP antibodies.
