ELECTRON PARAMAGNETIC RESONANCE (EPR) SPECTROMETER

我们申请共享仪器资助，购买布鲁克EMX系列电子顺磁共振（EPR）光谱仪，用于生化和医学研究。该系统将用于逐步淘汰莱斯大学生物化学和细胞生物学的老化瓦里安E-6机器。对这种光谱仪的需求在多个层面上是合理的：* 在德克萨斯大学休斯顿医学院和莱斯大学的生物化学和生物物理研究中，EPR技术的使用稳步增加。为了保证EPR设备的可靠性，以进行持续的研究和培训，我们选择购买Bruker EMX EPR光谱仪，因为它的耐用性和使用性。* EPR是一种强有力的工具，在结构分析的许多生物系统，涉及有机自由基和过渡金属中心。这种EPR能力将与UT休斯顿医学院的结构生物学中心整合，以补充现有的核磁共振（NMR）设施，并与该中心即将招聘的X射线晶体学家。* EPR系统将继续并扩大服务范围，为加入休斯顿地区分子生物物理培训计划的广泛用户提供服务，从而加强UT医学院，赖斯大学，贝勒医学院和休斯顿大学科学家之间的科学互动。

We apply for a shared instrument grant to purchase a Bruker EMX series electron paramagnetic resonance (EPR) spectrometer to be used for biochemical and medical research. This system will be used to gradually phase out the aged Varian E-6 machine at Rice University, Biochemistry and Cell Biology. Demand for this spectrometer is justified at multiple levels: * A steady increase in usage of EPR technologies in biochemical and biophysical studies at the University of Texas Medical School at Houston and at Rice University. To guarantee a reliable EPR facility for ongoing research and training purposes, we chose to buy the Bruker EMX EPR spectrometer for its durability and use of use. * EPR is a powerful tool in the structural analysis of the many biological systems that involve organic radicals and transition metal centers. This EPR capability will integrate with the Structural Biology Center at the UT-Houston Medical School to complement the existing nuclear magnetic resonance (NMR) facility and with the Center's imminent recruitment of a X-ray crystallographer. * The quested EPR system will continue and expand service to a wide spectrum of users joining the Houston Area Molecular Biophysical Training Program, thus strengthening the scientific interactions among scientists at UT Medical School, Rice University, Baylor College of Medicine and University of Houston.
