PrintFriendly and PDF


ProteoSys (PSY) is a private German biotechnology research institution (SME) mainly working in research projects in the fields of neurobiology, cancer, gerontology and toxicology. Our research is/has been partly funded by grants from National German agencies (BMBF) and the European Commission (FP5-FP7). We have established a technology platform for quantitative and differential analysis of protein biomarker signatures. Our expertise and focus is the discovery, validation and development of protein biomarkers for large scale testing in diagnostic clinical settings or the use of dynamic protein biomarker signatures for therapeutic development, therapy monitoring and molecular assessment of side effects. Current and finalised EU projects: Neurocypres, ESNATS, ReProTect; MiMage; Neupro-CF, Fight-MG.
