The Translational 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, and to more than 50,000 antibodies from the Human Protein Atlas.

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.

Recent Projects

Research Projects

  • Analysis of more than 1000 dried blood spot samples collected during early Covid19 pandemic to analyze the antibody response against Sars-Cov-2 in the Stockholm population using a multiplex serology approach
  • Profiling of host proteins associated to the envelope of SARS-CoV-2 using a bead-based strategy to detect intact enveloped virus particle in solution and multiplex immunoassay.
  • 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.
