  • Applikationshinweise
    Prostaglandin E (PGE ) is identical across all species and we expect this kit may measure PGE from sources other than human.
    The end user should evaluate recoveries of PGE in other samples being 2 tested.
    This assay has been validated for saliva, urine, serum, EDTA and heparin plasma samples and for tissue culture samples.
    A general cyclooxygenase inhibitor, such as meclofenamic acid or indomethacin at 15 μM should be added immediately after collection of any biological samples, such as serum and plasma.
    All samples should be frozen rapidly in dry ice/ethanol and stored at -80 °C.
    Samples containing visible particulates should be centrifuged prior to use.
    Severely hemolyzed samples should not be used in this kit.
    All samples with high lipid content may interfere with the measurement of PGE and may be extracted as described below.
    The normal reference range for serum Prostaglandin E (containing COX inhibitors) is 25-1,000 2 pg/mL.
    Typical normal mouse PGE serum levels are 45-150 ng/mL.
    Normal 24-hour urine PGE 2 2 levels are between 400-620 ng/24 hours.

    Sample values: Eight human serum samples that did not contain COX inhibitors were tested in the assay.
    Neat sample were diluted 1:20-1:50 in Assay Buffer and adjusted values ranged from 652 to 4,170 pg/mL with an average of 2,126 pg/mL.
    Ten human plasma samples that did not contain COX inhibitors were tested in the assay.
    Neat sample were diluted 1:20-1:50 in Assay Buffer and adjusted values ranged from 219 to 4,328 pg/mL with an average of 1,717 pg/mL.
    Eight normal human urine samples were diluted 1:10- 1:20 in Assay Buffer and adjusted values ranged from 56.9 to 326 pg/mL with an average of 149.9 pg/mL

    Protokoll
    This 2 EIA kit allows for the widest variations in sample size, sensitivity and assay timing of any A PGE standard is provided to generate a standard curve for the assay and all samples should be read off the standard curve.
    Standards or diluted samples are pipetted into a clear microtiter plate coated with an antibody to capture mouse IgG.
    A PGE -peroxidase conjugate is added to the standards and samples in 2 the wells.
    The binding reaction is initiated by the addition of a monoclonal antibody to PGE to 2 each well.
    After incubation, the plate is washed and substrate is added.
    The substrate reacts with the bound PGE -peroxidase conjugate.
    After a short incubation, the reaction is stopped and the 2 intensity of the generated color is detected in a microtiter plate reader capable of measuring 450nm wavelength.
    The concentration of the PGE in the sample is calculated, after making 2 suitable correction for the dilution of the sample, using software available with most plate readers.
    Aufbereitung der Reagenzien

    Allow the kit reagents to thaw and come to room temperature for 30-60 minutes.
    We recommend that all standards and samples be run in duplicate to allow the end user to accurately determine prostaglandin E concentrations.
    Ensure that all samples have reached room temperature and 2 have been diluted as appropriate prior to running them in the kit.

    Once diluted this is stable at 4 °C for 3 months.
    Wash buffer Dilute Wash Buffer Concentrate 1:20 by adding one part of the concentrate to nineteen parts of deionized water.
    Once diluted this is stable at room temperature for 3 months.

    Determine the number of wells to be used and return unused wells to the foil pouch with desiccant.
    Seal the ziploc plate bag and store at 4ºC.
    2. Pipet 50 μL of samples or standards into wells in the plate.
    3. Pipet 75 μL of Assay Buffer into the non-specific binding (NSB) wells.

    5. Add 25 μL of the DetectX® Prostaglandin E Conjugate to each well using a repeater pipet. 2
    6. Add 25 μL of the DetectX® Prostaglandin E Antibody to each well, except the nsb wells, 2 using a repeater pipet.

    8b. Shake the plate in a plate shaker at room temperature for 15 minutes to ensure adequate mixing of the reagents. Incubate at 4 °C for 16-18 hours.
    9. If using Option 8b., the following day remove the TMB Substrate from the refrigerator and allow to come to room temperature for at least 30 minutes. Addition of cold substrate will cause depressed signal.
    10. Aspirate the plate and wash each well 4 times with 300 μL wash buffer. Tap the plate dry on clean absorbent towels.
    11. Add 100 μL of TMB Substrate to each well, using a repeater pipet.
    12. Incubate the plate at room temperature for 30 minutes without shaking.
    13. Add 50 μL of the Stop Solution to each well, using a repeater pipet.
    14. Read the optical density generated from each well in a plate reader capable of reading at 450 nm.
    15. Use the plate reader's built-in 4PLC software capabilities to calculate prostaglandin E 2 concentration for each sample.

    Ergebnisberechnung

    Average the duplicate OD readings for each standard and sample.
    Create a standard curve by reducing the data using the 4PLC fitting routine on the plate reader, after subtracting the mean OD's for the NSB.
    The sample concentrations obtained, calculated from the %B/B0 curve, should be multiplied by the dilution factor to obtain neat sample values.

    Hintergrund
    Eicosanoid signal transduction pathways are highly conserved and are involved in a number of physiological processes. Prostaglandins are synthesized from arachidonic acid by cyclooxygenase (COX)-1 or -2, which convert the acid into PGH . This is further processed by cytosolic or microsomal prostaglandin 2 synthases to become PGE or one of several other prostanoids1-3. Prostacyclin is 2 the major cyclooxygenase product in blood vessel walls and it is present in Prostaglandin E 2 inflammatory fluids in similar concentrations to PGE . Prostacyclin is a potent vasodilator and 2 is more potent than PGE in producing hyperalgesia4.
