    1. Prepare all reagents, samples and standards,
    2. Add 25μL standard or sample to each well. Incubate 1 hours at 37 °C,
    3. Aspirate and add 25μL prepared Detection Reagent A. Incubate 1 hour at 37 °C,
    4. Aspirate and wash 3 times,
    5. Add 25μL prepared Detection Reagent B. Incubate 30 minutes at 37 °C,
    6. Aspirate and wash 5 times,
    7. Add 25μL Substrate Solution. Incubate 10-20 minutes at 37 °C,
    8. Add 20μL Stop Solution. Read at 450nm immediately.
    Préparation des réactifs
    1. Bring all kit components and samples to room temperature (18-25 °C) before use. If the kit will not be used up in one time, please only take out strips and reagents for present experiment, and leave the remaining strips and reagents in required condition.
    2. Standard - Reconstitute the Standard with 0.5 mL of Standard Diluent, keep for 10 minutes at room temperature, shake gently (not to foam). The concentration of the standard in the stock solution is 1.000ng/mL. Prepare 5 tubes containing 0.6 mL Standard Diluent and produce a triple dilution series by transferring 300 µL each. Mix each tube thoroughly before the next transfer. Set up 5 points of diluted standard such as 1,000ng/mL, 333.33ng/mL, 111.11ng/mL, 37.04ng/mL, 12.35ng/mL, and the last microcentrifuge tube with Standard Diluent is the blank as 0ng/mL.
    3. Detection Reagent A and Detection Reagent B - If lyophilized reconstitute the Detection Reagent A with 150μL of Reagent Diluent, keep for 10 minutes at room temperature, shake gently (not to foam). Briefly spin or centrifuge the stock Detection A and Detection B before use. Dilute them to the working concentration 100-fold with Assay Diluent A and B, respectively.
    4. Wash Solution - Dilute 10 mL of Wash Solution concentrate (30x) with 290 mL of deionized or distilled water to prepare 300 mL of Wash Solution (1x).
    5. TMB substrate - Aspirate the needed dosage of the solution with sterilized tips and do not dump the residual solution into the vial again.

    Note:

    1. Making serial dilution in the wells directly is not permitted.
    2. Prepare standard within 15 minutes before assay. Please do not dissolve the reagents at 37 °C directly.
    3. Please carefully reconstitute Standards or working Detection Reagent A and B according to the instruction, and avoid foaming and mix gently until the crystals are 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 for once pipetting.
    4. The reconstituted Standards, Detection Reagent A and Detection Reagent B can be used only once.
    5. Prepare Substrate working Solution within 15 minutes before assay.
    6. If crystals have formed in the Wash Solution concentrate (30x), warm to room temperature and mix gently until the crystals are completely dissolved.
    7. Contaminated water or container for reagent preparation will influence the detection result.
    Préparation de l'échantillon
    • It is recommended to use fresh samples without long storage, otherwise protein degradation and denaturation may occur in these samples, leading to false results. Samples should therefore be stored for a short period at 2 - 8 °C or aliquoted at -20 °C (≤1 month) or -80 °C (≤ 3 months). Repeated freeze-thaw cycles should be avoided. Prior to assay, the frozen samples should be slowly thawed and centrifuged to remove precipitates.
    • If the sample type is not specified in the instructions, a preliminary test is necessary to determine compatibility with the kit.
    • If a lysis buffer is used to prepare tissue homogenates or cell culture supernatant, there is a possibility of causing a deviation due to the introduced chemical substance. The recommended dilution factor is for reference only.
    • Please estimate the concentration of the samples before performing the test. If the values are not in the range of the standard curve, the optimal sample dilution for the particular experiment has to be determined.
    Précision du teste
