Produktbeschreibung

The Human Peroxisome Activated Receptor Delta (PPARd) ELISA Kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of PPARd in human tissue homogenates and other biological fluids. Detection Range: 0.156-10ng/ml Sensitivity: <0.057ng/ml Precision: Intra-Assay: CV<10% Inter-Assay: CV<12% Storage and Stability: Desiccation recommended. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20C upon receipt. Store all other reagents at 4C. Stable for 6 months after receipt of order. Test Principle: The microtiter plate provided in this kit has been pre-coated with an antibody specific to PPARd. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to PPARd. 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 PPARd, 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 PPARd in the sample is then determined by comparing the O.D. of the sample to the standard curve. Kit Components: *027380A: Microtiter Plate, 1x96 wells, Pre-coated, ready to use *027380B: Standard, 2x1vial 027380C: Standard Diluent, 1x20ml *027380D: Detection Reagent A, 1x120ul *027380E: Detection Reagent B, 1x120ul 027380F: Assay Diluent A, 1x12ml 027380G: Assay Diluent B, 1x12ml 027380H: TMB Substrate, 1x9ml 027380K: Stop Solution, 1x6ml 027380L: Wash Buffer, 30X, 1x20ml Storage and Stability: Store *027380A, *027380B, *027380D and *027380E at -20C. Store all the other components at 4C. Unused kit is stable for 6 months. 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. Materials Required But Not Supplied: 1. Microplate reader with 450 10nm filter. 2. Precision single or multi-channel pipettes and disposable tips. 3. Eppendorf Tubes for diluting samples. 4. Deionized or distilled water. 5. Absorbent paper for blotting the microtiter plate. 6. Container for Wash Solution Sample Preparation and Storage: Tissue Homogenates: The preparation of tissue homogenates will vary depending upon tissue type. For this assay, tissues were rinsed thoroughly in ice-cold PBS (0.02M pH 7.0-7.2) to remove excess blood and weighed before homogenization. The tissues were minced to small pieces and homogenized in 5-10ml of PBS with a glass homogenizer on ice (Micro Tissue Grinders works too). The resulting suspension was sonicated with an ultrasonic cell disrupter or subjected to two freeze-thaw cycles to further break the cell membranes. After that, the homogenates were centrifuged for 5 minutes at 2500*g. The supernatant was removed and assayed immediately or aliquoted and stored at -20C or lower. Other Biological Fluids: Centrifuge samples for 20 minutes at 1000*g. Remove particulates and assay immediately or store samples in aliquots at -20C or -80C. Avoid repeated freeze/thaw cycles. Note: 1. Samples to be used within 5 days may be stored at 4C, otherwise samples must be stored at -20C (1 month) or -80C (2 months) to avoid loss of bioactivity and contamination. 2. Sample hemolysis will influence the results so hemolyzed Assay Procedure Summary: 1. Prepare all reagents, samples and standards. 2. Add 100ul standard or sample to each well. Incubate 2 hours at 37C. 3. Aspirate and add 100ul prepared Detection Reagent A. Incubate 1 hour at 37C. 4. Aspirate and wash 3 times. 5. Add 100ul prepared Detection Reagent B. Incubate 30 minutes at 37C. 6. Aspirate and wash 5 times. 7. Ad
