    摘要: The present invention relates to novel arginine analogs, and methods for their synthesis and use. Such analogs are designed to provide a protected or free thiol (—SH) group, thereby providing a convenient linkage chemistry for coupling to a suitable group on a target such as a protein, polypeptide, detectable label or solid phase, and at a site distal to the guanidino group. Arginine analog conjugates are useful for generating antibodies that can bind specifically with dimethylarginine, which can be detected using such antibodies in immunoassays.

    摘要: The present invention relates to the identification and use of polypeptides that bind to antibodies directed to a desired polypeptide of interest. Using natriuretic peptides and their precursors, and in particular BNP, as an example, the present invention describes a number of natriuretic peptides fragments produced in biological samples, most preferably blood-derived samples, that bind to antibodies directed to BNP. Because production of such fragments is an ongoing process that may be a function of, inter alia, the elapsed time between onset of an event triggering natriuretic peptide release into the tissues and the time the sample is obtained or analyzed; the elapsed time between sample acquisition and the time the sample is analyzed; the type of tissue sample at issue; the storage conditions; the quantity of proteolytic enzymes present; etc., such fragments may be used when both designing an assay for one or more natriuretic peptides, and when performing such an assay, in order to provide an accurate prognostic or diagnostic result.

    摘要: Antibodies and methods are described for the detection and quantitation of cardiac specific troponin I in samples. Cardiac-specific troponin isoforms exist in various forms in the blood, including free and complexed forms. By selecting antibodies that are insensitive and/or sensitive to these various forms, the present invention can provide immunoassays that more accurately reflect the clinical state of an individual. These described antibodies and methods can be used for providing indicators of myocardial infarction and other cardiac pathologies.

    摘要: Assay systems and specialized antibodies for the detection and quantitation of troponin I and troponin T in body fluids as an indicator of myocardial infarction. Since troponin I and T exist in various conformations in the blood, the ratios of the monomeric troponin I an T and the binary and ternary complexes, as well as which form of troponin present in the blood, may be related to the metabolic state of the heart. Disclosed is a system to determine the presence of a troponin form or a group of troponin forms in a sample of whole blood, serum or plasma.Disclosed is a stabilized composition of troponin; the stabilized composition can comprise a stabilized composition of troponin I, wherein the troponin I is oxidized, the troponin I can be unbound or the troponin I can be in a complex.Disclosed is a method for improving the recovery of troponin I or T from a surface used in immunoassays.Also disclosed are antibodies which recognize, unbound troponin forms, the forms of troponin in binary complexes, the ternary complex of troponin I, T and C, and the conformations of troponin I having intramolecularly oxidized and reduced cysteines.

    摘要: A fluorometer for sensing the fluorescence of a sample utilizes an optical energy source for exciting a sample to be tested and an optical energy detector for detecting the emitted energy from the excited sample. Drive electronics are used for positioning the sample with respect to the optical components allowing a plurality of sample regions to be tested. A processor is utilized to control the operation of the test in accordance with test instructions and for processing the emitted energy detected from the sample to determine test results. A ROM chip socket accepts a plurality of ROM chips, wherein each ROM chip stores test data sets for one or more test types to be performed. ROM chips can be swapped to allow the fluorometer to be configured and reconfigured to perform a plurality of different tests. A communications interface facilitates the sharing of test information between the fluorometer and external entities.
