特徴

• The Total Bile Acid (TBA) BioAssay™ ELISA Kit is a quantitative competitive assay for the detection of TBA in human serum, plasma and other biological fluids. Cell lysates and tissue homogenates, though not tested, may potentially be used as samples.
• Detection Range:0.312-20nmol/ml
• Sensitivity:0.188nmol/ml
• Precision: Intra-Assay CV: <8%Inter-Assay CV: <10%
• Assay Principle:This ELISA kit employs the quantitative competitive enzyme-linked immunoassay technique, utilizing a microtiter plate provided in this kit has been pre-coated with TBA. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to TBA. 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 TBA, 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 TBA in the sample is then determined by comparing the O.D. of the sample to the standard curve.
