It’s personal

Improving the lives of patients is a personal matter for each and every member of our team at Protagen. You’ll see this in the passion we apply to the discovery, identification, and validation of novel biomarker panels for better diagnostic (Dx) and companion diagnostic (CDx) tests. It is demonstrated by the commitment and expertise we bring to our partnerships when working on clinical development programs. Our dedication to advancing diagnostics for personalized medicine is evident in everything we do.

Diagnostics Differentiated

We are adding a new dimension to the world of diagnostics. Our SeroTag biomarker development engine delivers unique biomarker signatures. The disease-specific signatures that we identify, often based on novel markers, are the basis for new diagnostic strategies that will improve the differentiation and stratification of patients. The result is a new medical scenario in which disease states are recognized earlier, and medical care can be more specifically and effectively provided.
