Proteomics Biomedicum Core Facility - our offer

The Proteomics Biomedicum Core Facility provides services using best available mass spectrometry-based proteomics techniques and methods with focus on quantitative proteomics, including single cell proteomics. We help designing experiments, providing a broad range of efficient samples preparation methods, high quality mass spectrometric data as well as data analysis and interpretation.

The Proteomics Biomedicum Core Facility offers services to analyse proteins using a wide range of mass spectometry based analytical methods with focus on quantitative proteomics, both label-free and multiplexed TMT-labeling.

We have recently established an experimental workflow that allows us to analyse extremely low amounts of proteins extracted from single cells and generate quantitative results with reasonable depth of the proteome. Similarly, we are now able to work with a low number of cells, which previously has been a challenge when samples were available in limited amounts.

Based on our experiences, accumulated over the years, we are eager to discuss projects related to identification and quantification of proteins and assist with experimental design as well as to deliver high quality results.
