    Spezifität
    This assay has high sensitivity and excellent specificity for detection of Mouse CST3.
    Kreuzreaktivität (Details)
    Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between the target antigen and all analogues for other species. Therefore, cross reaction may still exist.

  • Applikationshinweise
    • The supplier is only responsible for the kit itself, but not for the samples consumed during the assay. The user should calculate the possible amount of the samples used in the whole test. Please reserve sufficient samples in advance.
    • Samples to be used within 5 days may be stored at 2-8°C, otherwise samples must be stored at -20°C (≤ 1 month) or -80°C (≤ 2 months) to avoid loss of bioactivity and contamination.
    • Grossly hemolyzed samples are not suitable for use in this assay.
    • If the samples are not indicated in the manual, a preliminary experiment to determine the validity of the kit is necessary.
    • Please predict the concentration before assaying. If values for these are not within the range of the standard curve, users must determine the optimal sample dilutions for their particular experiments.
    • Tissue or cell extraction samples prepared by chemical lysis buffer may cause unexpected ELISA results due to the impacts of certain chemicals.
    • Owing to the possibility of mismatching between antigens from another resource and antibodies used in this supplier's kits (e.g., antibody targets conformational epitope rather than linear epitope), some native or recombinant proteins from other manufacturers may not be recognized by this supplier's products.
    • Influenced by factors including cell viability, cell number and cell sampling time, samples from cell culture supernatant may not be recognized by the kit.
    • Fresh samples without long time storage are recommended for the test. Otherwise, protein degradation and denaturalization may occur in those samples and finally lead to wrong results.

    Detection wavelength: 450 nm

    Information on standard material:
    Depending on the antigen to be detected, standards can be either native or recombinant protein. The recombinant proteins are being expressed in CHO cells in most cases. Please inquire for more information. The formulation of auxiliary material in the standard is considered proprietary information, however it does not contain any poisonous substance. Proclin 300 (1:3000) is used as preservative.

    Information on reagents:
    In most cases the stop solution provided is 1 N H2SO4. The formulation of wash solution is proprietary information. None of the components contain (sodium) azide, thimerosal, 2-mercaptoethanol (2-ME) or any other poisonous materials. For the sandwich method kits, the sample diluent, antibody diluent, enzyme diluent and standard all contain BSA.

    Information on antibodies:
    The antibodies provided in different kits vary in regards to clonality and host. Some antibodies are affinity purified, some are Protein A

    Protokoll
    Antibody specific for CST3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any CST3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CST3 is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of CST3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
    Aufbereitung der Reagenzien
    • Biotin-antibody (1×) - Centrifuge the vial before opening.
      Biotin-antibody requires a 100-fold dilution. The suggested dilution is 10µL of Biotin-antibody + 990µL of Biotin-antibody Diluent.
    • HRP-avidin (1×) - Centrifuge the vial before opening.
      HRP-avidin requires a 100-fold dilution. The suggested dilution is 10µL of HRP-avidin + 990µL of HRP-avidin Diluent.
    • Wash Buffer (1×) - If crystals have formed in the concentrate, warm up to room temperature and mix gently until the crystals have completely dissolved. Dilute 20mL of Wash Buffer Concentrate (25×) into deionized or distilled water to prepare 500mL of Wash Buffer (1×).
    • Standard - Centrifuge the standard vial at 6000-10000rpm for 30s.
      Reconstitute the Standard with 1ml of Sample Diluent. Do not substitute other diluents. This reconstitution produces a stock solution of 200pg/mL. Mix the standard to ensure complete reconstitution and allow the standard to sit for a minimum of 15 minutes with gentle agitation prior to making dilutions.
      Pipette 250µL of Sample Diluent into each tube. Use the stock solution to produce a 2-fold dilution series. Mix each tube thoroughly before the next transfer. The undiluted Standard serves as the high standard (200pg/mL). Sample Diluent serves as the zero standard (0ng/mL).
    Note:
    • Kindly use graduated containers to prepare the reagent. Please don't prepare the reagent directly in the Diluent vials provided in the kit.
    • Bring all reagents to room temperature (18-25°C) before use for 30 min.
    • Prepare fresh standard for each assay. Use within 4 hours and discard after use.
    • Making serial dilution in the wells directly is not permitted.
    • Please carefully reconstitute Standards according to the instruction. Avoid foaming and mix gently until the crystals have completely dissolved. To minimize imprecision caused by pipetting, use small volumes and ensure that pipettors are calibrated. It is recommended to suck more than 10µL when pipetting.
    • It is recommended to use distilled water to prepare reagents and samples. Using contaminated water or container for reagent preparation will influence detection result.

    Full Protocol
    • 1. All reagents in the ELISA kit were brought up to room temperature (RT) before use.
    • 2. 100 µL of each sample was added per well to the micro ELISA plate well. All samples and standards were assayed in triplicate. Plate was covered with sealer (provided in kit) and incubated for 2h at 37°C.
    • 3. After incubation, liquid in each well was removed by suction.
    • 4. 100 µL of Biotin-antibody (1X) was added per well. Plate was covered with sealer and incubated for 60 min at 37°C.
    • 5. Wells were washed with 200 µL of wash buffer three times. Each wash involved fully aspirating the liquid from each well by pipette. After the last wash the plate was inverted against clean absorbent paper to remove any remaining liquid.
    • 6. 100 µL of HRP-avidin (1x) was added per well. The plate was covered with sealer and incubated for 60 mins at 37°C.
    • 7. Wells were washed with 200 µL of wash buffer five times same as step 5.
    • 8. 90 µL of TMB Substrate was added to each well and the plate was covered with a new plate sealer. The plate was tapped to ensure mixing and incubated at 37°C in the dark.
    • 9. After 30 min, when an apparent gradient appeared in the standard wells, the reaction was terminated by adding 50 µL of Stop Solution to each well.
    • 10. The optical density (OD value) of each well was immediately read using a micro-plate reader set to 450 nm (with reference set to 570nm).
    • 11. The triplicate readings for each standard were averaged and the average zero standard optical density subtracted. A standard curve was generated by plotting the normalized OD value for each standard on the y-axis against the concentration on the x-axis using Excel. A line of best fit through the points on the graph was used to generate the equation x = (y+0.0048) / 0.0249.
    • 12. The equation x = (y+0.0048) / 0.0249 was used to calculate Cys-C concentrations of the samples based on their normalized average OD values.
