Abstract:
The invention provides among other things an assay method that compensates for the presence of endogenous antibodies, e.g., autoantibodies, which might otherwise compromise the measurement of an analyte in a biological sample. In one embodiment, this method entails the use of a two labeled entities: a labeled detection agent and a labeled species-specific antibody, wherein the labeled species-specific antibody is specific for the species from which the biological sample was obtained. Sample analyte is bound by the detection agent and any anti-analyte autoantibodies present in the sample. Analyte bound by autoantibodies is detected via the species-specific antibody, optionally labeled.
Abstract:
The present disclosure relates to isolated human autoantibodies and assays and kits for detecting human autoantibodies reactive with at least one natriuretic peptide or natriuretic peptide fragment in a test sample.
Abstract:
The invention provides among other things methods and kits based on assaying for cardiac troponin autoantibodies, either in conjunction with an assay for cardiac troponin and/or as an independent indicator of cardiac pathology, such as myocarditis, cardiomyopathy, and/or ischemic heart disease. Assay methods of the invention can be employed among other things to identify cardiac pathology, or risk thereof, in subjects who have an autoimmune disease or who are related to an individual with an autoimmune disease. In particular embodiments, the invention also provides a method of determining whether a subject having, or at risk for, a cardiac pathology is a candidate for immunosuppressive therapy or immunoabsorption therapy. The invention also provides kits and kit components that are useful for performing the methods of the invention.
Abstract:
A method of assessing whether or not erythrocytes are suitable for transfusion into a recipient comprising (i) assaying a sample of erythrocytes for free choline, and (ii) comparing the level of free choline in the sample with the level of free choline deemed suitable for transfusion therapies; and a kit for use in such a method comprising at least one reagent for assaying the sample, instructions for conducting the assaying of the sample, and guidelines for assessing the suitability of the erythrocytes for transfusion.
Abstract:
Provided herein among other things are diagnostic tests, methods of use, and kits for the assessment and management of cardiovascular autoimmune disease and risk of cardiovascular autoimmune disease. Assay methods of the invention can be employed among other things to identify cardiovascular autoimmune disease, or risk thereof, in subjects who have cardiovascular disease, an autoimmune disease, or who are related to an individual with an autoimmune disease. The method can be employed for testing of a subject that exhibits symptoms of cardiovascular disease, as well as of a subject that is apparently healthy and does not yet exhibit symptoms of cardiovascular disease, but may with time. In one embodiment, the invention also provides a method of determining whether a subject having, or at risk for, a cardiovascular disease is a candidate for immunosuppressive therapy or immunoabsorption therapy. The invention also provides kits and kit components that are useful for performing the methods of the invention.
Abstract:
5(6)-methyl substituted fluorescein derivatives and a process for producing 5(6)-methyl substituted derivatives. Also provided are methods for these utilizing these derivatives as indicator reagents in assays for analytes, indicator reagents which comprise specific binding members attached to these derivatives and test kits which contain these derivatives.
