Mass Spectrometry

Q Exactive HF

In 2016, we acquired this quadrupole-Orbitrap with an ultra-high-field analyzer as part of the Z project of SFB 1177 (Molecular and Functional Characterization of Selective Autophagy). It provides high sensitivity and acquisition speed for complex samples, especially in conjunction with the hyphenated UHPLC which allows the use of smaller column particles and longer columns due to higher pressure resistance of the fluidics (up to 1200 bar).

Orbitrap Fusion LUMOS

Since November 2018, the unit houses an Orbitrap Fusion Lumos mass spectrometer, which was partially funded by the DFG (FUGG 161/922-1). This so-called “Tribrid”-MS, adding a third mass analyzer (ion trap) to the above-mentioned quadrupole-Orbitrap configuration, allows us to perform SPS-MS3 analyses providing increased accuracy for TMT-based quantitative proteomics experiments. As for the Q Exactive HF, it is coupled to an EASY nLC 1200 for high sensitivity chromatographic separations.

Two DIONEX U3000 HPLC

_{(one analytical, one micro) with fraction collection option}

Used to prefractionate peptides using highPh-reversed phase chromatography for increased coverage of identified proteins and PTM-sites in proteomics samples.

If you wish to set up a new collaboration with us, or are planning mass spectrometry experiments as part of the SFB 1177, always contact us before starting the experiments. 
Members of the SFB 1177 with projects requiring MS analysis should contact our service platform team for a first consultation via email. Afterwards, please register to MS Portal and complete the sample submission form.

For external researchers use of the MS platform is possible on the basis of collaboration. Please contact Christian Münch or one of the IBC2 group leaders with whom you wish to collaborate directly to discuss the options.

Christian Münch studied Biochemistry at the University of Tübingen and the Max Planck Institutes in Martinsried and Tübingen. He obtained his PhD from the University of Cambridge (UK) where he performed his thesis work in Anne Bertolotti’s laboratory at the Laboratory of Molecular Biology (Cambridge, UK). His graduate work focused on the folding and prion-like properties of mutant SOD1 in the context amyotrophic lateral sclerosis, and earned him the prestigious British Neuroscience Association Postgraduate Award. After his graduation, Christian joined the laboratory of Wade Harper at the Harvard Medical School with an EMBO long-term fellowship to study protein quality control in mitochondria, particularly the mitochondrial unfolded protein response. Christian started as an independent group leader at the Institute of Biochemistry II in December 2016. His main research interests focus on mitochondrial quality control, in particular in determining the processes involved in the mitochondrial unfolded protein response and its role in human diseases.

Georg studied human and molecular biology and did his PhD at the biochemical engineering institute (Prof. Elmar Heinzle), at Saarland university. During his thesis, he worked on organotypic cultures of hepatocytes for in vitro toxicology and implemented a LC-MALDI platform for the analysis of their secreted proteins. He then moved to Alain van Dorsselaer´s lab at CNRS Strasbourg working as a postdoc in the field of mass spectrometry-based quantitative proteomics within national and european projects. Georg joined the Mass Spectrometry Unit at the IBC2 in September 2017 and is responsible for method development, sample preparation, and maintenance of the mass spectrometry platform.

In 2012, Martin graduated as Biological Technical Assistant (BTA) in Koblenz and started working in the Kerschensteiner laboratory at the Institute of Clinical Neuroimmunology in Munich focusing on protein production for the MS research. From 2016 till 2019, he was part of the research group Schmidt at the Institute for Microscopic Anatomy and Neurobiology in Mainz, gaining further experience in the production and purification of proteins for cancer research. In 2020, Martin joined the IBCII to support the Protein Quality Control Group of Christian Münch and the Quantitative Mass Spectrometry Unit.
