Mass spectrometry plays a key role in molecular level research and is central to 'omics' research, i.e., proteomics, metabolomics, lipidomics, glycomics, as well as materials research, nutrition, drug discovery, reproductive biology, environmental chemistry and biology. The ILSB-MSL is staffed by highly skilled technical staff and state-of-the-art instrumentation to provide advanced MS research capabilities to support a broad range of molecular-level research and develop projects and train scientists to advance the field of mass spectrometry to new levels. The ILSB-MSL specializes MS in peptide mass mapping, protein ID, proteomics and lipidomics, as well as advanced research capabilitiesthat challenge routine technologies, viz. ultra-high resolution MS, ion mobility-MS, and native MS/IMMS in support of studies of large proteins and membrane protein complexes. Challenging research problems often require development of new methodologies and/or modifications of existing approaches; consequently, many of these projects are handled as collaborative research projects. We strongly encourage researchers to consult with us about their project first, before samples are submitted for analysis.
