C-Reactive Protein (CRP) BioAssay™ ELISA Kit (Canine)

The C-Reactive Protein (CRP) BioAssay™ ELISA Kit is a quantitative sandwich assay for the detection of CRP in canine serum, plasma, tissue homogenates and other biological fluids.||Detection Range:|0.313-20ng/ml||Sensitivity:|<0.188ng/ml||Precision:|Intra-Assay CV: <8%|Inter-Assay CV: <10%||Assay Principle:|This ELISA kit employs the sandwich enzyme-linked immunoassay technique, utilizing a microtiter plate pre-coated with an antibody specific to CRP. Standards and samples are added to the appropriate wells, then incubated. Aspirate and wash the plate. The Antibody (Biotin) is added to all the wells. The plate is incubated and then washed. Streptavidin (HRP) is added to each microplate well and incubated then washed. Then the TMB substrate solution is added and incubated. After the TMB substrate solution is added, only those wells that contain CRP, the antibody (Biotin) and Streptavidin (HRP) 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 CRP in the sample is then determined by comparing the O.D. of the sample to the standard curve.||Kit Components:|*354973A: Microtiter Strips, 1x48 wells or 1x96 wells.|*354973B: Standard, 1x1vial or 2x1 vial|354973C: Sample/Standard Dilution Buffer, 1x10ml or 1x20ml|354973D: Antibody-Biotin (Concentrated), 1x60ul or 1x120ul|354973E: Antibody Dilution Buffer, 1x5ml or 1x10ml|354973F: Streptavidin (HRP) (SABC, 1x60ul or 1x120ul|354973G: SABC Dilution Buffer, 1x5ml or 1x10ml|354973H: TMB Substrate, 1x5ml or 1x10ml|354973J: Stop Solution, 1x5ml or 1x10ml|354973K: Wash Buffer, 25X, 1x15ml or 1x30ml||Storage and Stability:|Store unopened *354973A at 4ºC; store at -20ºC once opened.
