The BioAssay ELISA Kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Cell Division Cycle Protein 20 Homolog (CDC20) in human serum, plasma, cell culture supernatants, cell lysates, tissue homogenates and body fluids. This kit for research use only, not for therapeutic or diagnostic applications.Assay Principle:Cell Division Cycle Protein 20 Homolog (CDC20) BioAssay ELISA Kit (Human) utilizes the quantitative Competitive Enzyme Immunoassay technique, utilizing a monoclonal antibody and an conjugate to Cell Division Cycle Protein 20 homolog (CDC20) (Human). The assay sample and buffer are incubated together with the HRP conjugate in a pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the Target Protein concentration since Protein from samples and Protein-HRP conjugate compete for the anti-Protein antibody binding site. Since the number of sites is limited, as more sites are occupied by Protein from the sample, fewer sites are left to bind the Protein-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Target Protein concentration in each sample is interpolated from this standard curve.Detection Range:1.0-25ng/mlSensitivity:0.1ng/mlPrecision:Intra-Assay %CV: 5.6, 7.2Inter-Assay %CV: 3.4, 4.8Specificity:This assay has high sensitivity and excellent specificity for detection of CDC20 (Human). No significant crossreactivity or interference with analogs was observed.Note: Crossreactivity detection between CDC20 and all analogs has not been determined and crossreaction may exist in some cases.Kit Components:185971A: Microtiter Strips, 1x96 wells185971B: Enzyme Conjugate, 1x6ml185971C: Standard, 0ng/ml, 1x1 vial185971D: Standard, 1.0ng/ml, 1x1 vial185971E: Standard, 2.5ng/ml, 1x1 vial185971F: Standard, 5.0ng/ml, 1x1 vial185971G: Standard, 10ng/ml, 1x1 vial185971H: Standard, 25ng/ml, 1x1 vial185971J: Substrate A, 1x6ml185971K: Substrate B, 1x6ml185971L: Stop Solution, 1x6ml185971M: Wash Solution, 100X, 1x10ml185971N: Balance Solution, 1x3mlStorage and Stability:Store components at 4°C.
