Find your service unit

The Autoimmunity Profiling and Affinity Proteomics units at SciLifeLab both specialize in proteomics but serve distinct research needs.

Autoimmunity Profiling

  • Focuses on analyzing the immune response, particularly autoantibodies and other immune markers.
  • Provides expertise in serology-based profiling to study autoimmunity across a wide range of conditions.
  • Offers services such as customized autoantigen microarrays for identifying disease-specific autoantibody patterns, and high-throughput serology to assess immune responses.
  • Ideal for researchers studying autoimmune diseases, vaccine responses, or general immunology​.

Affinity Proteomics

  • Centers on biomarker discovery, validation, and quantitative protein analysis.
  • Utilizes technologies like Proximity Extension Assays (PEA) and in situ PLA for sensitive and multiplexed protein detection.
  • Designed for large-scale studies involving protein-protein interactions, post-translational modifications, or quantification in body fluids, cells, and tissues.
  • Strongly supports clinical and translational research, including precision medicine applications​.

Key Differentiators

  • Autoimmunity Profiling is tailored to investigating immune responses and autoimmune markers, making it highly specialized for immunology-focused research.
  • Affinity Proteomics offers a broader platform for protein analysis across various biological and clinical contexts, including biomarker studies and quantitative assays.

Your choice should depend on the nature of your project. If your research is immunology-centered or involves autoimmune responses, the Autoimmunity Profiling unit would be more appropriate. If you need comprehensive protein profiling or biomarker quantification, Affinity Proteomics might be the better fit.

Unit information

Autoimmunity Profiling

Skip to

Introduction

The Autoimmunity and serology profiling unit provides infrastructure and technologies for analysis of the autoantibody repertoire in body fluids and antibody validation using custom designed protein and peptide arrays.

Supported by the resource of more than 42 000 unique human protein fragments generated within the Human Protein Atlas, representing more than 18 000 human protein coding genes, we offer proteome wide screening for autoantibody reactivity on large microarrays, as well as downstream solutions for investigation of autoantibody repertoires in hundreds of patient samples in parallel. Instrumentation and know-how is available for generating customized spotted protein microarrays as well as measurement and analysis of commercially available protein microarrays.

News

  • The unit is soon set to increase its services in serology by incorporating a multi-disease serology panel into its offerings. This panel includes a wide range of different variants of the SARS-CoV-2 proteins, spike representations of SARS, MERS, and antigen representations of the four coronaviruses causing common cold. It will additionally include influenza virus antigens representing the glycoproteins hemagglutinin and neuraminidase, as well as antigen representations of RSV, Mpox, adenovirus, metapneumovirus, and parainfluenza virus. A full list of the currently included antigens and further information on the project can be found at the Multi-disease serology dashboard at the Swedish Pathogens Portal.
  • The main lab have gone through a reconstruction to reach bio safety level 2 standard which enable a higher throughput of biological samples requiring a higher level of safety.

Services

Proposed projects are assessed and prioritized according to the following model.

1) Initial assessment by unit:

  • Technical feasibility and suitability
  • Required capacity and resources for the project

2) Project prioritization by committee:

  • Scientific potential
  • Supporting preliminary data
  • Significance of unit specific technique for project
  • Supports unit development (competence and techniques)

Applications

  • Profiling the autoantibody repertoire in plasma, serum or CSF by screening on microarrays of randomly selected antigens.
  • Verification of autoantibody profiles on suspension bead arrays with selected antigens.
  • Epitope mapping and off-target analysis of affinity reagents as well as identified autoantibodies on antigen or peptide microarrays.

Using the unit

Please fill in the Project proposal form and we will come back to you shortly after to further discuss the details of your request. However, we strongly recommend that the National Bioinformatics Infrastructure Sweden, NBIS, is contacted for a free consultation or drop-in session prior to filling in a project proposal.

Affinity Proteomics

Skip to

Introduction

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.

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.

News

The Affinity Proteomics-Stockholm 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 personalized medicine.

Project prioritization and cost model

The unit provides service for clinical and translational research on a first-come first-served basis. Projects with principal investigators from Swedish Universities are prioritized over projects from non-Swedish universities and industry. Collaborative development projects are prioritized based on the expected importance of the development work for future research service projects or healthcare applications. Project requests are typically directed to a specific node depending on the research question and what assay to use.

Academic users benefit from a subsidized cost including assay dependent reagents, and a user fee, including instrument related cost and consumables. An hourly fee can be added for experimental work exceeding the normal cost for the assay. For industry we apply a full-cost model, always including hourly fee. Collaborative projects can be further subsidized or covered by joint grants.
