Assays
KCAS has developed hundreds of analytical methods. The assays listed below include our non-proprietary methods. The majority of assays we develop are confidential and proprietary, and we are constantly developing additional methods.
If you do not see a method you need, please contact us, as we may have the method in development or similar compound expertise. We welcome requests for assays to meet your specific needs.
Our non-proprietary assays and biomarkers are listed below in alphabetical order. By clicking on the analyte name, you can download specific information on the assay, including method type, matrix, analytical range(s), and stability data.
