    Laboratory Research Human Copeptin ELISA Assay Kit 96 Wells Size With Strong Sensitivity

    Laboratory Research Human Copeptin ELISA Assay Kit 96 Wells Size With Strong Sensitivity


    Cat.No E1129Hu

    Standard Curve Range: 0.05ng/ml - 20ng/ml

    Sensitivity: 0.024ng/ml

    Size: 96 wells

    Storage: Store the reagents at 2-8°C. For over 6-month storage refer to the expiration date keep it at -20°C. Avoid repeated thaw cycles. If individual reagents are opened it is recommended that the kit be used within 1 month.

    *This product is for research use only, not for use in diagnosis procedures. It’s highly recommend to read this instruction entirely before use.


    Assay Procedure

    1. Prepare all reagents, standard solutions and samples as instructed. Bring all reagents to room temperature before use. The assay is performed at room temperature.

    2. Determine the number of strips required for the assay. Insert the strips in the frames for use. The unused strips should be stored at 2-8°C.

    3. Add 50μl standard to standard well. Note: Don’t add antibody to standard well because the standard solution contains biotinylated antibody.

    4. Add 40μl sample to sample wells and then add 10μl anti-Copeptin antibody to sample wells, then add 50μl streptavidin-HRP to sample wells and standard wells ( Not blank control well ). Mix well. Cover the plate with a sealer. Incubate 60 minutes at 37°C.

    5. Remove the sealer and wash the plate 5 times with wash buffer. Soak wells with at least 0.35 ml wash buffer for 30 seconds to 1 minute for each wash. For automated washing, aspirate all wells and wash 5 times with wash buffer, overfilling wells with wash buffer. Blot the plate onto paper towels or other absorbent material.

    6. Add 50μl substrate solution A to each well and then add 50μl substrate solution B to each well. Incubate plate covered with a new sealer for 10 minutes at 37°C in the dark.

    7. Add 50μl Stop Solution to each well, the blue color will change into yellow immediately.

    8. Determine the optical density (OD value) of each well immediately using a microplate reader set to 450 nm within 10 minuets after adding the stop solution.

    Precision

    Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.

    Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

    CV(%) = SD/mean x 100

    Intra-Assay: CV<8%

    Inter-Assay: CV<10%

    Precautions

    • Prior to use, the sandwich ELISA kit and sample should be warmed naturally to room temperature 30 minutes.
    • This instruction must be strictly followed in the experiment.
    • Once the desired number of strips has been removed, immediately reseal the bag to protect the remain from deterioration. Cover all reagents when not in use.
    • Make sure pipetting order and rate of addition from well-to-well when pipetting reagents.
    • Pipette tips and plate sealer in hand should be clean and disposable to avoid cross-contamination.
    • Avoid using the reagents from different batches together.
    • Substrate solution B is sensitive to light, don’t expose substrate solution B to light for a long time.
    • Stop solution contains acid. Please wear eye, hand and skin protection when using this material. Avoid contact of skin or mucous membranes with kit reagent.
    • The kit should not be used beyond the expiration date.

    Summary

    1. Prepare all reagents, samples and standards.

    2. Add sample and ELISA reagent into each well. Incubate for 1 hour at 37°C.

    3. Wash the plate 5 times.

    4. Add substrate solution A and B. Incubate for 10 minutes at 37°C.

    5. Add stop solution and color develops.

    6. Read the OD value within 10 minutes.


    Calculation of Result

    Construct a standard curve by plotting the average OD for each standard on the vertical (Y) axis against the concentration on the horizontal (X) axis and draw a best fit curve through the points on the graph. These calculations can be best performed with computer-based curve-fitting software and the best fit line can be determined by regression analysis.
