Myostatin BioAssay(TM) ELISA Kit ( Mouse)

Myostatin (GDF8, Growth Differentiation Factor 8, MSTN) is a member of the transforming growth factor beta superfamily that is essential for proper regulation of skeletal muscle mass.Myostatin is a secreted protein that negatively regulates skeletal muscle mass determining both muscle fiber number and size. The myostatin pathway is conserved and regulates muscle mass in a number of animal species ranging from fish to humans. Inhibition of myostatin using a variety of therapeutic approaches can increase muscle mass in a number of animal models of human disease, including muscular dystrophy. \n\nIntended use:\nThe kit is a sandwich enzyme immunoassay for in vitro quantitative measurement of MSTN in mouse serum, plasma and other biological fluids.\n\nTest Principle:\nThe microtiter plate provided in this kit has been pre-coated with an antibody specific to MSTN. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific for MSTN. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain MSTN, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm пїЅ 10nm. The concentration of MSTN in the samples is then determined by comparing the O.D. of the samples to the standard curve.\n\nRange: 78.5-5000pg/ml\nSensitivity: 33pg/ml\nIntra-Assay: CV<10%\nInter-Assay: CV<12%\n\nKit Components:\n*M9875-11A: Microtiter Strip, 1x96wells Pre-coated, ready to use\n*M9875-11B: Standard, 2x1vial \nM9875-11C: Standard Diluent, 1пїЅ20ml\n*M9875-11D: Detection Reagent A, 1пїЅ120ul \n*M9875-11E: Detection Reagent B, 1пїЅ120ul \nM9875-11F: Assay Diluent A, 1x12ml\nM9875-11G: Assay Diluent B, 1x12ml\nM9875-11H: TMB Substrate 1пїЅ9ml\nM9875-11J: Stop Solution 1x6ml\nM9875-11K: Wash Buffer, 30X 1x20ml \n\nPrecaution:\nM9875-11J: Stop Solution suggested for use with this kit is an acid solution.
