  • Background

    How a therapeutic antibody is metabolized in the body is pertinently relevant to its efficacy. Therefore, pharmacokinetics study is an important part of the drug development.

    PD-1 is probably the most targeted molecule in today’s pharmaceutical industry, thanking to the clinical success of Keytruda® and Opdivo®. Many investigational anti-PD-1 mAbs are being developed. There is a growing need for a standard assay that can be used to facilitate the study of their pharmacokinetics.

  • Assay Principles

    The enclosed ELISA assay kit for anti-PD-1 h-mAb in human serum is based on an enzyme immunoassay (ELISA) between recombinant PD-1 protein (ECD) and a biotinylated anti-PD-1 monoclonal antibody. The method employs the principle of competitive ELISA, allowing quantification of monoclonal anti-PD-1 antibodies in human serum.

    The assay only involves the following steps:

    1. Coat the plate with human PD-1;

    2. Add the mixture of your sample and biotinylated anti-PD-1 antibody;

    3. Add Streptavidin-HRP followed by TMB or other colorimetric HRP substrate;

    4. Record the OD readings and analyze the serum concentration.

  • Reconstitution

    See Certificate of Analysis for details of reconstitution instruction and specific concentration.

  • Advantages

    Wide Coverage
    This kit has been tested for multiple investigational PD-1 antibodies, as well as the commercially available Keytruda® and Opdivo®. There is no requirement for the species and subtype of the antibody.

    Easy Process
    There is no longer a need to generate anti-drug antibodies for PK studies.

    Clean Result
    The use of the biotinylated antibody in the competitive ELISA significantly alleviates the issue of background noise issue that often occurs in traditional ELISA method.

  • Storage

    Upon receipt, please store all items at -20℃.

    After reconstitution, the stock solution should be kept at -80℃.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. Room temperature (RT) for 1 month in lyophilized state;

    2. -20℃ for 1 year in lyophilized state;

    3. -80℃ for 4 months under sterile conditions after reconstitution.
