Affinity Proteomics

Twitter: @plasmaprofiling

The Unit of Affinity Proteomics offers a long-standing expertise in the analysis of human body fluids, cells, and tissue lysates. We also provide analysis of protein-protein interactions and activation in situ or in tissues. Our services aim to support researchers and clinicians in the fields of translational and personalized medicine providing access to an exquisite infrastructure to apply cutting edge immunoassays technologies for multiplexed protein quantification.

With our expertise, we support biomarker studies from discovery to validation, in a large number of samples and a variety of human conditions. Our services include all aspects such as  study design, selection of antibodies, data processing and we also develop alternative assays tailored for the specific needs of the user’s projects.
