Purchase of 900 MHz NMR Spectrometer

描述（由申请人提供）：我们建议建立一个900mhz核磁共振的落基山脉地区核磁共振中心，服务于落基山脉和中部地区的大量大学。核磁共振中心将位于科罗拉多大学健康科学中心的新菲茨西蒙斯校区，将为蛋白质、核酸和碳水化合物结构和功能领域的核磁共振结构生物学家提供高效的研究服务。用户组由8个机构的19名研究人员组成。菲茨西蒙斯新基础研究大楼的空间是专门为900 MHz核磁共振的独特选址要求而设计的，大楼的建设正在顺利进行。trosy型实验的最新发展允许在比以前可能的更大的大分子上获得极高分辨率的核磁共振光谱。这些TROSY实验在超高场中进行了优化，并且所要求的最先进的900 MHz核磁共振光谱仪和冷冻探针将使用户能够利用这些强大的新技术。该中心的主要目标将是提供对900 MHz核磁共振独特功能的常规访问，以加速其生物和生物医学研究计划。除了在现场获取他们的核磁共振数据外，有经验的用户将能够在设施工作人员的帮助下通过互联网获取900 MHz核磁共振数据。核磁共振中心的第二个主要目标是建立并维护一个基于web的协作中心，以便在六个“重点领域”共享信息和专业知识。这些重点领域是用户组的优势所在，协作馆将为有经验的用户与其他用户分享他们的专业知识提供有价值的机制。核磁共振中心和网络合作馆的六个初步重点领域是：提高蛋白质核磁共振研究的分辨率和灵敏度；大型大分子配合物的核磁共振研究蛋白质和核酸动力学研究；RNA和DNA核磁共振研究的改进方法膜蛋白的核磁共振研究利用反胶束在低粘度溶剂中提高光谱分辨率。

DESCRIPTION (provided by applicant): We propose to establish a Rocky Mountain Regional NMR Center with a 900 MHz NMR serving a large number of Universities in the Rocky Mountain and Central Regions. The NMR Center will be situated on the new Fitzsimons campus of the University of Colorado Health Sciences Center, and will serve a productive group of NMR structural biologists in the areas of protein, nucleic acid and carbohydrate structure and function. The user group consists of 19 researchers at 8 Institutions. Space in the new Basic Research Building at Fitzsimons has been specifically designed for the unique siting requirements of a 900 MHz NMR and construction of the building is well underway. Recent developments in TROSY-type experiments allow acquisition of extremely high resolution NMR spectra on much larger macromolecules than was previously possible. These TROSY experiments are optimized at ultra-high fields, and the requested state-of-the-art 900 MHz NMR spectrometer and cryoprobe will make it possible for the users to take advantage of these powerful new techniques. The primary goal of the Center will be to provide routine access to the unique capabilities of the 900 MHz NMR in order to accelerate their biological and biomedical research programs. In addition to acquiring their NMR data on-site, experienced users will be able to acquire 900 MHz NMR data over the Internet with the aid of facility staff. A second major goal of the NMR Center will be to establish and maintain a Web-based collaboratorium for sharing information and expertise in a set of six "focus areas." These focus areas are strengths of the user group and the collaboratorium will provide a valuable mechanism for experienced users to share their expertise with other users. The six initial focus areas for the NMR Center and Web collaboratorium are: Improved Resolution and Sensitivity for NMR Studies of Proteins; NMR Studies of Large Macromolecular Complexes; Studies of Protein and Nucleic Acid Dynamics; Improved Methods for NMR Studies of RNA and DNA; NMR Studies of Membrane Proteins; and Improved Spectral Resolution by Employing Reverse Micelles in Low Viscosity Solvents. A well designed organizational plan for administering the facility is presented which is modeled after plans at other established multi-user NMR and synchrotron facilities. Time on the 900 MHz NMR will be allocated based on written proposals which will be reviewed by a proposal review committee. NIH-funded research that requires the high field, high resolution, and unique capabilities of the 900 MHz NMR will be the highest priority for the center.
