A total infrastructure of over 90 state-of-the-art mass spectrometers are available in eleven transnational access sites.
With over 30 Orbitrap’s, more than 10 Q – TOF’s, and 5 Triple Quad’s, the platform also houses a series of MALDI-TOF/TOF’s and FT-ICR high resolution instruments. Different access sites will host projects with different requirements (e.g. PTM analysis, membrane protein analysis, Bio-imaging, native structure analysis, native MS).
As a complement to the mass spectrometry focused sites, the KTH Access site offers antibody based imaging to study spatial proteomics in situ. The KTH access site provides single cell analysis via high-throughput imaging using a wide collection of antibodies from the Human Protein Atlas to study protein location at the single cell level or highly multiplexed imaging of 30 proteins using the CODEX platform.

The instruments include 10 of the latest generation of Q Exactive HF-X mass spectrometers exhibiting improved speed and sensitivity, and one Orbitrap Fusion Lumos mass spectrometer providing complementary fragmentation techniques and scanning techniques, such as ETD and MS3 acquisition.
Mass Spec Instruments
This facility houses nine mass spectrometers, which are equipped for nanoLC-MS/MS proteomics-type experiments.
The instruments include state-of-the-art technologies like high-resolution Orbitrap mass spectrometry, CID, HCD, electron transfer dissociation (ETD), and combinations thereof (EThcD), and cross-linking MS.
Collectively, the analytical technologies provide a full-spectrum infrastructure for high throughput and in-depth proteome analysis. Based on the broad fundament of methodological expertise and know-how, also targeted MS-based approaches, including selected reaction monitoring (SRM) and parallel reaction monitoring (PRM), as well as data independent acquisition (DIA)
Mass Spectrometers
Expertise
The infrastructure boasts the latest hardware for proteomics including three Orbitrap Fusion Lumos instruments (equipped with electron-transfer dissociation, ETD or ultra-violet photo-dissociation, UVPD) and three Orbitrap Q-Exactive HF-X instruments. The Orbitrap instruments are furnished with ultra-high performance nano-liquid chromatography systems. This outstanding equipment base enables proteomic projects at any scale and ranging from high-throughput discovery (data-dependent acquisition, DDA), targeted (parallel reaction monitoring, PRM) and data-independent (DIA) experiments.
Mass Spec Instruments
This facility houses 8 mass spectrometers, all coupled to sensitive nano-LC chromatography systems.
In combination with PSD, CID, HCD and ETD peptide fragmentation possibilities, these instruments enable high-throughput analysis of complex proteome samples as well as intact protein measurements. In addition, workflows for targeted MS-based approaches, including selected/parallel reaction monitoring (SRM/PRM) and data independent acquisition (DIA) are in place.

This facility operates one off-line HPLC system and two dedicated ultra-high-pressure liquid chromatography (UHPLC) systems coupled with a high field hybrid quadruple-orbitrap mass spectrometer (QExactive-HF) and has additional access to an identical instrument setup is also available at the centralized Consortium (COGENTECH) of the Campus, when additional measurement is needed.
This MS platform is integrated to an ample set of consolidated biochemical and analytical protocols for histone, protein, peptide, modified peptide and sub-proteomes purification prior to MS-analysis. Standard Data-dependent acquisition (DDA) methods are normally used, but hybrid DDA-single reaction monitoring (SIM) can also be employed to specifically target modified peptides in complex matrices.

The Cell Profiling facility is a Swedish national facility located at SciLifeLab but is also open for international users via the European EPIC XS network. The facility enables researchers to access the resources and expertise from the Human Protein Atlas and the primary aim is to do full service immunofluorescence projects at moderate to high-throughput level. Based on the resource of more than 25,000 antibodies and a panel of >20 different human cell lines, this facility has a unique position to investigate subcellular spatial proteomics for human and rodent biology (service area 1). Since 2020, the facility is also offering highly multiplexed imaging (up to 30 markers) of tissue sections using the CODEX platform (service area 2).
