85-4648-46　Interferon Gamma Receptor-2 (IFN-gamma R2) BioAssay™ ELISA Kit (Human) 48Tests　369992

特徴

• The Interferon Gamma Receptor-2 (IFN-gamma R2) BioAssay™ ELISA Kit is a quantitative sandwich assay for the detection of IFN-gamma R 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 IFN-gamma R2. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to IFN-gamma R2. 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 IFN-gamma R2, 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 IFN-gamma R2 in the sample is then determined by comparing the O.D. of the sample to the standard curve.
