The human Tenascin X （TNX） BioAssay ELISA Kit is a quantitative sandwich assay for the detection of TNX in human serum，plasma，tissue homogenates and other biological fluids.Detection Range：1.563-100ng/mlSensitivity：<0.938ng/mlAssay Principle：The microtiter plate provided in this kit has been pre-coated with an antibody specific to TNX. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to TNX. Streptavidin conjugated to Horseradish Peroxidase （HRP） is added to each microplate well and incubated. After TMB substrate solution is added，only those wells that contain TNX，Biotin-conjugated antibody and enzyme-conjugated Streptavidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of TNX in the sample is then determined by comparing the O.D. of the sample to the standard curve.Kit Components：*359403A： Microtiter Strips，8x12 wells.*359403B： Standard，2 vials359403C： Sample/Standard Dilution Buffer，1x20ml359403D： Antibody-Biotin （Concentrated），1x120ul359403E： Antibody Dilution Buffer，1x10ml359403F： Streptavidin-HRP Conjugate （SABC），1x120ul359403G： SABC Dilution Buffer，1x10ml359403H： TMB Substrate，1x10ml359403J： Stop Solution，1x10ml359403K： Wash Buffer （25X），1x30mlStorage and Stability：Store unopened *359403A at 4ºC; store at -20ºC once opened. Store unopened *359403B at 4°C; once reconstituted store at 4°C for up to 12 hours or at -20°C for up to 48 hours. Store other components at 4°C. Kit is stable for 6 months after receipt. For maximum recovery of product，centrifuge the original vials after thawing and prior to removing the cap.Assay Summary：1.
