As our name implies we apply mass spectrometry in a biological context. We are a research group and the Mass Spectrometry Research Core Facility of the Swammerdam Institute for Life Sciences of the University of Amsterdam. We apply mass spectrometry to a variety of biological questions from within the institute and our main focus areas are proteomics (bottum-up) and metabolomics (untargeted, LC-MS based).
We cover the large part of bottom up proteomics applications and also some limited intact protein analysis.
- Quantitative Proteomics (Label-Free, SILAC/15N metabolic, Isobaric chemical labelling).
- Proteome Wide Translation and Degradation rates (Pulsed SILAC/TMT, Pulsed SILAC-AHA).
- Deep Phosphoproteome analysis.
- Protein Analytics: sequence confirmation, ptm-mapping, holo-mass determination.
- Protein interactions: CO-IP, CHIP-SICAP, IP-MS, Thermal Proteome Profiling.
- Low sample input proteomics for rare cells or small tissue sections.
As mass spectrometrists we routinely measure small molecules, our metabolomics focus is untargeted quantitative metabolomics.
- Untargeted metabolomic profiling of Polar and Apolar metabolites.
- Targeted metabolomic profiling of large metabolite sets.
- Low sample input metabolomics.
- Biodiversity & ecology
- Biomedical & health
- Agri & Food
- Industrial biotech
- Untargeted LCMS based Metabolomics Analysis.
- Proteomics and Metabolomics Data Processing.
- Advanced protocols for low input sample preparation (TMT, MBR).
- Chemical Biology Expertise in Proteomics (Click Chemistry, AHA-Pulse labelling).
- Microbiology (focus on spore proteomics)
- Green Life Sciences
- Cell and Systems Biology
Expertise and Track Record
We are experienced mass spectrometrists operating state of the art equipment, as such we cover an important part of proteomics and metabolomics sample analysis as do others. What sets us apart, are some unique applications we have developed over the years.
1) Chemical Biology: AHA-pulse labelling to quantify proteome wide protein synthesis rates.
2) Bacterial spore proteomics for a variety of food spoiling and medically relevant organisms.
3) High sensitivity measurements of low input samples: i.e. from rare cells or small tissue sections.
4) Protein-Protein and Protein-Metabolite/Compound interaction studies.
- PH2: a kinase controlling vacuolar acidification in plant cells. (NWO-ALW, F Quattrocchio 2017-2020) Here we deliver phosphoproteomics and subcellular proteomics to unravel vacuolar acidification in Petunia.
- The molecular basis for Endospore Heterogeneity. (NWO-ALW S. Brul 2017-2020) We provide our signature spore proteomics approaches to unravel bacterial spore heterogeneity.
We have participated in a large number of cross technology projects over the years. Most often this involves integrating a variety of ‘omics’ data to answer a research question or combining with other techniques as follow up from a proteomics/metabolomics screen.
A number of publications of integrative projects are listed in the references below, we always provided either protein/proteomics or metabolite/metabolomics data to a study.
