Description
Intended Uses: For the quantitative detection of Pig Cardiac Troponin T (cTn-T) concentration in serum, plasma and other biological fluids.
Principle of the Assay::This assay employs a two-site sandwich ELISA to quantitate cTn-T in Pig serum, plasma. An antibody specific for cTn-T has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any cTn-T present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for cTn-T is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of cTn-T bound in the initial step. The color development is stopped and the intensity of the color is measured.
Background/Introduction: cTnT is located on the thin filament of striated muscles and regulates muscle contraction in response to alterations in intracellular calcium ion concentration. Mutations in this gene have been associated with familial hypertrophic cardiomyopathy as well as with restrictive and dilated cardiomyopathy. Transcripts for this gene undergo alternative splicing that results in many tissue-specific isoforms, however, the full-length nature of some of these variants has not yet been determined. Mutations of this gene may be associated with mild or absent hypertrophy and predominant restrictive disease, with a high risk of sudden cardiac death. Advancement to dilated cardiomyopathy may be more rapid in patients with TNNT2 mutations than in those with myosin heavy chain mutations
