10) Protein Interactions Core (Mvszka. Director)OverviewOur Protein Interaction Core will tap into an existing Core facility that is part of the University of Utah'sHealth Sciences Core facilities. The Protein Interaction Core facility was established in 1996 to provideinternal and external academic users access to state-of-the-art, label-free, real-time interactiontechnologies. Over the past 10 years, this facility has contributed to more than 100 research projectsthat encompass a wide array of biological areas.The Protein Interaction Core is centrally located within the School of Medicine (Rm 4A416) on theHealth Sciences campus. The laboratory's 1600 square feet of space was entirely renovated in 1997and was specifically designed to accommodate the Core facility's equipment and personnel. Currently,the facility maintains 7 surface plasmon resonance-based optical biosensors: 3 Biacore 2000s, 1 Biacore3000, 1 Biacore S51, 1 Biacore Flexchip, and 1 Lumera Proteome Processor. The Biacore 2000/3000platforms are ideal for measuring protein-protein interactions, while the Biacore S51 is designed forsmall-molecule interaction analysis. The Flexchip and Proteome Processor instruments are array-basedimaging systems that allow one to study up to 1000 binding partners immobilized onto the sensorsurface at one time. The Core has worked closely with both Biacore and Lumera on the development ofthis new hardware, as well as data analysis software. In early 2007, we plan to add a new biosensor(the ProteOn XPR36 from BioRad Laboratories) to our Core, funded by ab NIH Shared InstrumentGrant. Together, these state-of-the-art instruments allow us to measure the interactions of biomoleculessuch as proteins, oligonucleotides, and lipids in high-resolution, as well as high-throughput, formats.Experiments are scheduled through email contacts with the Core's manager. Typically, the investigatorand their staff then meet with the manager to plan the best course of action for the proposed study.Samples are then dropped off at the Core and experiments are initiated the same day. This ensures thatlabile samples are able to be processed in a timely manner.
