The UC Proteomics Laboratory (UCPL) is fully equipped with the protein separation and mass spectrometry equipment as well as the trained personnel to perform comparative analyses of complex protein mixtures and to identify the differentially-expressed proteins. Proteomics laboratory personnel also offer guidance to the research community regarding the feasibility of a given approach and/or advice on proteomics experimental design to enhance the probability of success. Please contact the lab director to set up a consultation.
The research expertise in the UC Proteomics Laboratory provides the identification of differentially expressed proteins and the characterization of protein modifications (e.g. phospho, ubiquitin, glyco). Furthermore, various heavy isotope tagging (e.g. TMT) and label-free methods are used to both identify the proteins and quantify the changes in abundance. Additional research-oriented projects include methods to quantify global changes in modifications from cell and tissues, proximity labeling (e.g., APEX/bioID) profiling, and mass spectrometry-based methods quantitation for proteins via surrogate peptides using SRM/MRM methodology.

Project Title: An Orbitrap Mass Spectrometry System for the University of Cincinnati Proteomics Laboratory Project Summary/Abstract This proposal requests funding for a nanoflow LC system coupled to a Q Exactive HF-X mass spectrometry system to be housed and used in the University of Cincinnati Proteomics Laboratory (UCPL). This system will support the NIH-funded research community across UC, Cincinnati Children's Hospital Medical Center (CCHMC) and the Cincinnati VA Medical Center. The new instrument is requested to maintain the high level of mass spectrometry-based proteomics support for the research community, which encompasses over 300 NIH- funded investigators with over 200 million dollars of support annually. The new instrument is needed to both improve the technical capabilities through increased sensitivity and to lessen the extended wait times for instrument access due to the increased number and complexity of research projects supported by the UCPL. The research support provided by the UCPL has expanded well beyond routine sample analysis and is now most often directed at more complex, research-oriented or sample-intensive studies that require the best sensitivity and greater instrument time. To support these projects, the UCPL is currently equipped with two mass spectrometers: 1) Sciex 4800 MALDI-TOF/TOF MS and 2) Sciex 5600+ Q-Tof, nanoLC-MS/MS system. However, the demand for nanoLC-MS/MS instrument has resulted in sample queues that are often 2-3 weeks long, which dramatically affects the ability to support the 30+ investigators each year. In addition, the MALDI- TOF/TOF system (purchased in 2005) has progressed to the point where the vendor can no longer ensure that the system can be repaired, and thus many of the routine analyses currently done on this system are being migrated to the only other available system, adding to the wait times. Specific areas of research for the Major User Groups include, global profiling of regulatory modifications such as phosphorylation and ubiquitination, detailed structural characterization of lipoproteins through cross-linking studies, evaluation and quantification of differential proteins in brain synapse function, and evaluation of large patient cohorts for the identification, quantification and validation of biomarkers of kidney diseases. The PI of the application has a long history (20+ years) of success in developing, adapting and applying biological mass spectrometry to solve research questions. More importantly, he works effectively at the interface of technology and biology as a collaborative partner with investigators to design experiments to maximize success. The requested system will be operated by a PhD scientist with 11 years of experience in all aspects of nanoLC-MS/MS analysis. Importantly, the UCPL is supported institutionally by the University of Cincinnati to offset the cost of service contracts and technology development and to help minimize the direct cost of services to the investigators. The requested instrument is ideally suited to address both the technical specifications and capacity issues for the 4 Major User Groups encompassing 8 NIH funded investigators.project_title:

DESCRIPTION (provided by applicant): This proposal requests funds to acquire a high resolution Fourier transform mass spectrometer and associated liquid chromatography system to support the NIH-funded research of investigators at the University of Cincinnati. This new instrumentation is intended to support on- going NIH-funded research into health-related issues such as antibiotic resistance, atherosclerosis, cancer, diabetes, infectious diseases and obesity. Specifically, the following types of analyses will be enabled by this acquisition: a) Metabolic flu measurements to identify key metabolic pathways in cardiometabolic diseases and various cancers; b) Metabolite identification to support identification of metabolic pathways revealed during metabolic flux measurements; and c) metabolomic characterization of lysophospholipid and cholesterol metabolic pathways. A key group of NIH-supported investigators at the University of Cincinnati will directly benefit from these new capabilities. Moreover, these new capabilities will stimulate these researchers and other biomedical investigators on campus to examine additional experiments that will benefit from this instrument. The NIH-funded researchers participating in this request require dedicated LC-MS/MS or high-resolution ESI/APCI-MS/MS capabilities to accomplish goals associated with their funded projects. The PI, who has been active in the field of mass spectrometry for over 20 years, will be responsible for the managerial oversight of the requested instrumentation. He will report to an external advisory board composed of scientists from within the university. The advisory board will establish scheduling priorities, work with the PI and accounting personnel to establish cost-recovery rates, and will serve as a resource for projecting future use of the requested equipment. The equipment will be housed in the University of Cincinnati Mass Spectrometry Facility. This 3,500 sq. ft. facility is equipped with the ancillary instrumentation required for biomolecule characterization. The instrumentation will be operated and maintained by two Ph.D.-level facility staff scientists, with one of these scientists being designated as the primary operator.project_title:
