Produktbeschreibung

The Free Haemoglobin (f-Hb) BioAssay(TM) ELISA Kit is a quantitative sandwich assay for the detection of f-Hb in human serum, plasma and other biological fluids. Cell lysates and tissue homogenates, though not tested, may potentially be used as samples. Detection Range: 0.313-20ng/ml Sensitivity: 0.188ng/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 f-Hb. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to f-Hb. 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 f-Hb, 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 f-Hb in the sample is then determined by comparing the O.D. of the sample to the standard curve.
