特徴

• The Thrombopoietin (TPO) BioAssay™ ELISA Kit (Human) is a quantitative sandwich assay for the detection of TPO in human serum, plasma and other biological fluids.
• Detection Range:31.25-2000pg/ml
• Sensitivity:<18.75pg/ml
• Precision: Intra-Assay CV: <8%Inter-Assay CV: <10%
• Assay Principle:The microtiter plate provided in this kit has been pre-coated with an antibody specific to TPO. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to TPO. 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 TPO, biotin-conjugated antibody and enzyme-conjugated streptavidin complex 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 TPO in the sample is then determined by comparing the O.D. of the sample to the standard curve.
