Applied Biomarkers and Immunoassays

Biological or pathological processes lead to changes in the composition of the proteome. Accurate analysis of such changes in individual proteins/biomarkers can be performed using antibody-based detection systems.
The Applied Biomarkers and Immunoassays group uses various immunoassay platforms for this purpose. The group contributes its technical and scientific know-how to contract research and service projects. The working group is involved in applied research projects with academic partners, as well as in industrial research collaborations and joint projects with partners from industry and academia.


Services are offered tailored to customers' questions and know-how is applied in research collaborations.
