Plasma Profiling

National facility

The Plasma Profiling Facility offers a long-standing expertise in affinity proteomic analysis of human body fluids. Our services aim to support researchers and clinicians in the fields of translational and personalized medicine. We provide 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, antibody validation, data processing and statistical analysis. And we also develop alternative assays tailored for the specific needs of the user's projects.

The facility hosts a unique combination of several advanced technologies and has direct access to more than 50,000 antibodies from the Human Protein Atlas.

The Plasma Profiling facility is now part of the Biomarker platform within the European infrastructure for translational medicine (EATRIS). EATRIS is a non-profit European Research Infrastructure Consortium (ERIC) which aims to facilitates collaboration among researchers, physicians, and developers and supports the establishment of multidisciplinary projects in the field of personalised medicine.

Research Projects:

  • Profiling 400 plasma samples for 1100 proteins using Olink ® technology for the discovery of protein-signatures in health and disease states
  • Evaluation and translation of a novel immunoassay for a cancer-related biomarker.
  • Profiling 3,000 plasma samples using a customized bead array with HPA antibodies for the discovery of disease-associated proteins. The aims are to identify and validate potential biomarkers; (1) to stratify populations by risk of disease progression, and (2) to monitor organ function in response to treatment.
  • Design of a new immunoassay to study proteins for their involvement in protein-protein interactions. We analyzed samples from immuno-precipitations derived from transfected human cells.
  • Development of a new immunoassay to validate proposed biomarker candidates by analyzing lysates of cells collected from cancer patients.
