特徴

• The NT-proBNP (N-Terminal Pro-Brain Natriuretic Peptide) BioAssay™ ELISA Kit (Human) is a quantitative sandwich assay for the detection of NT-proBNP in human serum, plasma and other biological fluids. Cell lysates and tissue homogenates, though not tested, may potentially be used as samples.
• Detection Range:39.063-2500pg/ml
• Sensitivity:<23.438pg/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 NT-proBNP . Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to NT-proBNP. 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 NT-proBNP, 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 NT-proBNP in the sample is then determined by comparing the O.D. of the sample to the standard curve.
