Company history

Founded in 1997, Protagen began life as a protein analysis services company, as a spin-out from the Ruhr-University of Bochum. In 2002, Protagen moved to its current location in the BioMedical Center (BMZ) Dortmund. 2010 saw Protagen strengthen its protein library and biomarker discovery capabilities, focusing on unmet diagnostic needs in autoimmune diseases by utilizing the power of autoantibodies. Its unique blend of experience and expertise in autoantibody serum screening, combined with the continuous improvement and optimization of biomarker development, has continued to push Protagen forward, leading to the establishment of the SeroTag® process in 2011/2012.

Today, Protagen is a leading industry provider, specializing in pharma development services, novel diagnostics, and companion diagnostics, in the field of immuno-oncology and autoimmune disease. By continuing to apply its proprietary SeroTag® biomarker discovery platform and its new portfolio of NavigAID patient stratification products, Protagen identifies valuable biomarkers that support pharmaceutical development and personalized treatment regimens.
