Section II: Object
Acquisition of an additional timsTOF Pro 2 system
Proteomics Research Infrastructure (PRI) is a state of-the-art mass spectrometry (MS)-based proteomics facility. Founded on 1 July 2020, the new facility provides coordinated, proprietary client access to forerunner proteomic technology, exceptional technical assistance, and streamlined bioinformatic data analysis for the local research community. PRI is funded by the Novo Nordisk Foundation (NNF) and linked to the NNF Center for Protein Research at the University of Copenhagen.
The timsTOF Pro 2 system comes with a dual-TIMS (trapped ion
mobility spectrometry) analyzer optimized for high-speed
shotgun proteomics. Its unique geometry allows incoming ions
to be accumulated in parallel in the first section, and for ions to
be released dependent on their mobility from the second
section of the dual-TIMS analyzer. This results in nearly 100%
duty cycle, making this parallel accumulation serial fragmentation technique (PASEF) perfectly suited for nanoflow
LC-MS analysis of enzymatically digested complex protein
Mixtures (Meier et al, Journal of Proteome Research 2015, Meier et al Bioarchive, 2019). The timsTOF Pro system provides a unique technology for the identification of peptides, which is highly relevant for the research performed at our facility. The timsTOF from Bruker is the only instrument in the market which has both TIMS and MS technology allowing the PASEF acquisition method. We are already using this technology in our infrastructure and need to increase the capacities due to a high demand in MS analyses.
Section IV: Procedure
- The works, supplies or services can be provided only by a particular economic operator for the following reason:
- protection of exclusive rights, including intellectual property rights
- Additional deliveries by the original supplier ordered under the strict conditions stated in the directive
The timsTOF Pro 2 system comes with the Trapped ion mobility which allows Parallel Accumulation Serial Fragmentation (PASEF) acquisition method to provide extremely high speed and sensitivity to reach new depths in shotgun proteomics. Bruker is the only provider for such instrument. Our collaborator laboratory at MaxPlanck institute for biochemistry, Munich had already tested this technology (Meier et al Bioarchive, 2018). We demonstrated that more than 800,000 fragmentation spectra in standard 120 min LC runs are easily achievable, which can be used for near exhaustive precursor selection in complex mixtures or re-sequencing weak precursors. Online PASEF achieves a remarkable sensitivity with more than 2,900 proteins identified in 30 min runs of only 10ng HeLa digest. This technology is highly relevant for high sample throughput and measurement of low input material samples, which is essential for the projects in our facility.
