    • 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.

    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%

    Assay Principle
    This Sandwich ELISA Kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Human CNKSR1 antibody. CNKSR1 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human CNKSR1 Antibody is added and binds to CNKSR1 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated CNKSR1 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Human CNKSR1. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

    Intended Use
    This sandwich kit is for the accurate quantitative detection of Human Connector Enhancer of Kinase Suppressor of Ras 1 (also known as CNKSR1) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.

    Specimen Collection
    Serum Allow serum to clot for 10-20 minutes at room temperature. Centrifuge at 2000-3000 RPM for 20 minutes.

    Plasma Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 15 minutes at 2000-3000 RPM at 2 - 8°C within 30 minutes of collection.

    Urine Collect by sterile tube. Centrifuge at 2000-3000 RPM for approximately 20 minutes. When collecting pleuroperitoneal fluid and cerebrospinal fluid, please follow the procedures above-mentioned.

    Cell Culture Supernatant Collect by sterile tubes when examining secrete components. Centrifuge at 2000-3000 RPM for approximately 20 minutes. Collect the supernatants carefully. When examining the components within the cell, use PBS (pH 7.2-7.4) to dilute cell suspension to the cell concentration of approximately 1 million/ml. Damage cells through repeated freeze-thaw cycles to let out the inside components. Centrifuge at 2000-3000 RPM for approximately 20 minutes.

    Tissue and other body fluids Rinse tissues in PBS (pH 7.4) to remove excess blood thoroughly and weigh before homogenization. Mince tissues and homogenize them in PBS (pH7.4) with a glass homogenizer on ice. Thaw at 2-8°C or freeze at -20°C. Centrifuge at 2000-3000 RPM for approximately 20 minutes.

    *Sample can't be diluted with this kit. Owing to the the material we use to prepare the kit, the sample matrix interference may falsely depress the specificity and accuracy of the assay.

    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-CNKSR1 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.
