Procollagen Type Ⅰ C-Terminal Propeptide (PICP) BioAssay ELISA Kit is a 1.5-hour solid-phase competitive ELISA designed for the quantitative determination of PICP in rat serum, plasma, cell culture supernatants, tissue homogenates and body fluids. This kit is intended for research use only and may not be used for therapeutic or diagnostic applications.Detection Range:1-25ng/mlSensitivity:0.1ng/mlPrecision:Intra-Assay %CV: <10Inter-Assay %CV: <10Specificity: This assay has high sensitivity and excellent specificity for detection of PICP (Rat). No significant crossreactivity or interference with analogs was observed. Note: Crossreactivity detection between the PICP and all analogs has not been determined and crossreaction may exist in some cases.Kit Components:202110A: Microtiter Strips, 1x48 wells or 1x96 wells. Pre-coated with anti-PICP antibody.202110B: Enzyme Conjugate, 1x3ml or 1x6ml202110C: Standard, 0ng/ml, 1x1 vial202110D: Standard, 1ng/ml, 1x1 vial202110E: Standard, 2.5ng/ml, 1x1 vial202110F: Standard, 5ng/ml, 1x1 vial202110G: Standard, 10g/ml, 1x1 vial202110H: Standard, 25ng/ml, 1x1 vial202110J: Substrate A, 1x6ml202110K: Substrate B, 1x6ml202110L: Stop Solution, 1x6ml202110M: Wash Solution, 100X, 1x10ml202110N: 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. Storage and Stability:Store components at 4°C. Stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap.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-PICP antibody. The assay samples and standards are incubated together with PICP-HRP conjugate for one hour. A competition for limited antibody binding sites on the plate occurs between PICP-HRP conjugate and PICP 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 PICP 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 PICP concentration in each sample is interpolated from this standard curve.Contact:United States Biological4 Technology WaySalem, MA 01970www.usbio.netTech Support: tech@usbio.netCustomer Service: service@usbio.netTel: 781-639-5092 • 800-520-3011Fax: 978-594-8052
