The C-Reactive Protein (CRP) BioAssay(TM) ELISA Kit is a sandwich ELISA for the in vitro quantitative determination of CRP concentrations in human serum, plasma and other biological fluids. Detection Range: 0.39-25ng/ml Sensitivity: 0.23ng/ml Precision: Intra-Assay %CV: <10% Inter-Assay %CV: <10% Specificity: Recognizes human CRP. No significant cross-reactivity or interference between human CRP and analogues was observed. Test Principle: The microtiter plate provided in this kit has been pre-coated with an antibody specific to CRP. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to CRP. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Free components are washed away. The substrate solution is added, only those wells that contain CRP, biotin-conjugated antibody and enzyme-conjugated Avidin will apear blue in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450nm 2nm. The OD value is proportional to the concentration of human CRP. The concentration of CRP in the sample is then determined by comparing the O.D. of the sample to the standard curve.

Store all the other components at 4C. Unused kit is stable for 6 months after receipt. Once kit components are opened, it is highly recommended to use remaining reagents within 1 month provided this is within the expiration date of the kit. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap. Assay Procedure Summary: 1. Prepare all reagents, samples and standards. 2.
