    Protocol
    The Adalimumab ELISA kit is designed to measure free Adalimumab with high specificity and sensitivity. This assay employs the sandwich enzyme immunoassay technique. A precoated anti-Adalimumab 96 well plate is provided. Calibrator, quality control samples and test samples are pipetted into the appropriate wells. Adalimumab present in biological matrices is bound by the immobilized capture antibody. After washing away any unbound substances, enzyme linked detection antibody is added to the wells. The plate is washed to remove any unbound antibody-enzyme reagent and a substrate solution is added to the wells for color development. The color development is proportional to the amount of Adaliumumab present in test samples and the concentration is calculated from the standard series.
    Reagent Preparation

    Prepare only the appropriate amount of required reagent on the day of use. Store all reagents as per instructions stated on the label. 1. Wash Buffer (1X) Preparation: Dilute wash buffer concentrate with ultra-pure water 1/10 before use (for example add 20 mL concentrate to 180 mL ultra-pure water). Mix well. 2. Detection Reagent (1X) Preparation: Dilute detection reagent with assay buffer 1/1000 before use (for example add 11 μL concentrate to 11 mL of assay buffer). Mix well. 3. Preparation of Calibrators: Prepare calibrators with concentrations ranging from 2,500 ng/mL to 78 ng/mL. The following is an example calibrator curve.

    Sample Collection
    This kit is compatible with EDTA-plasma, heparinplasma and serum samples. Samples can be stored at or below -20 °C for up to 1 year.
    Sample Preparation

    Dilute calibrators and test samples 1/50 with assay buffer (for example add 5μL of prepared calibrator or sample to 245μL of assay buffer). Mix well. Do not store diluted samples.

    Assay Procedure

    This assay employs the sandwich enzyme immunoassay technique. Anti- Adalimumab is coated onto a 96 well microplate. Calibrator, quality control samples and test samples are pipetted into the appropriate wells. Adalimumab present in biological matrices is bound by the immobilized capture antibody. After washing away any unbound substances, enzyme linked detection antibody is added to the wells. The plate is washed to remove any unbound antibody-enzyme reagent and a substrate solution is added to the wells for color development. The color development is proportional to the amount of Adalimumab present in test samples.

    Calculation of Results
    1. Construct a standard curve by plotting the absorbance obtained from each standard against concentration. Use a 4 or 5 parameter curve fit. Alternatively a log-log curve fit may be used. 2. The concentration of the unknowns can be read directly from this standard curve using the absorbance value for each sample. 3. Any sample undiluted or diluted still reading greater than the highest standard should be diluted appropriately with calibrator diluent and retested. If the samples have been diluted, the concentration determined from the standard curve must be multiplied by the dilution factor.
    Assay Precision
    Precision: The precision was determined by analyzing samples prepared at 313 ng/mL in 6 replicates on 6 different occasions. Intra-assay coefficient of variation (CV) < 10%. Inter-assay CV < 10%.

    Recovery: 250 ng/mL of Adalimumab was spiked in 10 lots of human serum. Recovery ranges are from 90-109% with an average recovery of 104%.
