Patent number: 9081009Abstract: Compositions, methods and devices for the detection of anti-lipoidal antibodies and the diagnosis of disease, for example, syphilis, are described. In particular, oxidized cardiolipins, which may be conjugated with a variety of attachment molecules, such as BSA, KLH, biotin, synthetic protein MAPS, IgY, streptavidin, or avidin, are described. Such oxidized cardiolipin, alone or complexed with one or more attachment molecules, are useful to detect anti-lipoidal antibodies (such as IgG and IgM antibodies) in subjects, for example, when used in ELISA plates. ELISA plates are described that permit the detection of anti-lipoidal antibodies and that permit the co-detection of nontreponemal and treponemal antibodies in biological samples.Type: GrantFiled: July 11, 2014Date of Patent: July 14, 2015Assignees: The United States of America as represented by the Secretary of the Department of Health and Human Services, Arlington Scientific Inc.Inventors: Arnold R. Castro, Himanshu Champaklal Mody

Patent number: 8394600Abstract: Compositions, methods and devices for the detection of anti-lipoidal antibodies and the diagnosis of disease, for example, syphilis, are described. In particular, a method for immobilizing a lipoidal antigen, comprising cardiolipin, lecithin, and cholesterol, on a solid support (such as a nitrocellulose membrane) is described. The ability to immobilize a lipoidal antigen on a membrane satisfies a long-felt need for a membrane-based assay for the detection of anti-lipoidal antibodies. Also described are immunoassay devices for concurrently performing treponemal and non-treponemal tests for syphilis.Type: GrantFiled: March 23, 2012Date of Patent: March 12, 2013Assignee: The United States of America as represented by the Secretary of the Department of Health and Human Services, Centers for Disease Control and PreventionInventor: Arnold R.
