Biomarker Assays

Biomarker assays are laboratory methods that detect or analyze genes, proteins, or other molecules in a patient’s biological sample (tissue, blood, or other fluid). Biomarker assays are fundamental tests in biotherapeutic drug monitoring, research, and development, as they directly assess the presence of a disease state or biological characteristic of interest.

Prolytix offers comprehensive coagulation assays and the ability to run the entire catalog of Meso Scale Discovery (MSD) biomarker assays off the shelf. Additionally, our team has extensive experience in the development, validation, and execution of custom biomarker assays.
