Thromboxanes B2 (TXB2) BioAssay ELISA Kit is a 1.5-hour solid-phase competitive ELISA designed for the quantitative determination of TXB2 in rat serum, plasma, tissue homogenates and body fluids. This kit is intended for research use only and may not be used for therapeutic or diagnostic applications.Assay Principle:This ELISA kit employs the quantitative competitive enzyme-linked immunoassay technique, utilizing a microtiter plate that has been pre-coated with a monoclonal anti-TXB2 antibody. The assay samples and standards are incubated together with TXB2-HRP conjugate for one hour. A competition for limited antibody binding sites on the plate occurs between TXB2-HRP conjugate and TXB2 in the samples and standards. 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 terminate 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 TXB2 concentration in the sample or standard. A standard curve is plotted relating the intensity of the color (O.D.) to the concentrations of the standards. The TXB2 concentration in each sample is interpolated from this standard curve.Detection Range: 100-2500pg/mlSensitivity: 1pg/mlPrecision:Intra-Assay %CV: <10Inter-Assay %CV: <10Specificity: This assay has high sensitivity and excellent specificity for detection of TXB2 (Rat). No significant crossreactivity or interference with analogs was observed. Note: Crossreactivity detection between the TXB2 and all analogs has not been determined and crossreaction may exist in some cases.Kit Components:204895A: Microtiter Strips, 1x48 wells or 1x96 wells204895B: Enzyme Conjugate, 1x3ml or 1x6ml204895C: Standard, 0pg/ml, 1x1 vial204895D: Standard, 100pg/ml, 1x1 vial204895E: Standard, 250pg/ml, 1x1 vial204895F: Standard, 500pg/ml, 1x1 vial204895G: Standard, 1000pg/ml, 1x1 vial204895H: Standard, 2500pg/ml, 1x1 vial204895J: Substrate A, 1x6ml204895K: Substrate B, 1x6ml204895L: Stop Solution, 1x6ml204895M: Wash Solution, 100X, 1x10ml204895N: Balance Solution, 1x3mlNote:The BALANCE SOLUTION is used only when the sample is cell culture supernatants, body fluid and tissue homogenate; if the sample is serum or plasma, then the BALANCE SOLUTION is a superfluous reagent.
