Assays

Our highly active Method Development group averages one new method per week. If you do not see an assay you need, please contact us, as we may have the method in development or similar compound expertise. We welcome requests for specific assays to meet your needs.

More than 3,800 proprietary and more than 800 non-proprietary assays show the depth of our experience. The following list displays ourĀ  non-proprietary methods and biomarkers in alphabetical order. By clicking on the analyte name, you can view and/or download information on the assay, including method type, matrix, analytical range(s) and stability data. For certain methods, additional calibration ranges are available. Click on the Contact Us button for more information about these assays or the development of proprietary assays for your specific application.
