Lysyl Oxidase Like Protein 2 (LOXL2) BioAssay(TM) ELISA Kit (Human)

Lysyl Oxidase Like Protein 2 (LOXL2) BioAssay(TM) ELISA Kit (Human) is a sandwich enzyme immunoassay for in vitro quantitative measurement of LOXL2 in human serum, plasma, tissue homogenates and other biological fluids. Detection Range: 0.156-10ng/ml, Sensitivity: 0.061ng/ml, Intra-Assay: CV<10%, Inter-Assay: CV<12%, Test Principle: The microtiter plate provided in this kit has been pre-coated with an antibody specific to LOXL2. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to LOXL2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain LOXL2, biotin-conjugated antibody and enzyme-conjugated Avidin 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 LOXL2 in the sample is then determined by comparing the O.D. of the sample to the standard curve. Kit Components: *026611A: Microtiter Strips, 1x48 wells or 1x96 wells, Pre-coated, ready to use, *026611B: Standard, 2x1 vial, 026611C: Standard Diluent, 1x10ml or 1x20ml, *026611D: Detection Reagent A, (green) 1x60ul or 1x120ul, *026611E: Detection Reagent B (red), 1x60ul or 1x120ul, 026611F: Assay Diluent A, 1x6ml or 1x12ml, 026611G: Assay Diluent B, 1x6ml or 1x12ml, 026611H: TMB Substrate, 1x4.5ml or 1x9ml, *026611J: Positive Control, 1.29ng/ml, 1x1vial (Lyophilized), 026611K: Stop Solution, 1x3ml or 1x6ml, 026611L: Wash Buffer, 30X, 1x10ml or 1x20ml, Precaution: The Stop Solution (026611K) provided for use with this kit is an acid solution. Wear eye, hand, face, and clothing protection when using this material. Storage and Stability: Store *026611A, *026611B, *026611D, *026611E and *026611J at -20°C. After reconstitution of *026611J, store at 4°C and use within 5 days. Store all the other components at 4°C. 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. Notes on 026611J: Positive Control , Intended Use:, The positive control is from a human serum sample known to contain the target protein. It will provide a positive result in the ELISA assay, which indicates that the kit is optimized and working properly. Characteristics: The positive control vial contains human LOXL2 in human serum (lyophilized powder). Note: The human based material used in this product is screened for HIV, Hepatitis A, B, C, HTLV and Syphilis. Expected Values: 1.29ng/ml, Usage: Dissolve with 150ul standard diluent and let stand for 10 minutes. If powder is partly insoluble, shake gently until fully dissolved. Mix gently before use. In the experiment, add 100ul to an appropriate well of the plate and test its concentration along with standards and your specimens. Note: Upon receipt store Positive Control vial at -20°C. After reconstitution, store Positive Control vial at 4°C and use within 5 days. Assay Procedure Summary: 1. Prepare all reagents, samples and standards., 2. Add 100ul standard or sample to each well.
