CONFOCAL EQUIPMENT FOR BIOMEDICAL & NANOMEDICINE: NEUROSCIENCES

该子项目是利用由NIH/NCRR资助的共享仪器赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是用于资助的，不一定是研究者的机构。描述（由申请人提供）：该提案要求资金购买具有FRET和TIRF显微功能的激光扫描共聚焦显微镜系统。仪器将存放在密苏里州大学道尔顿心血管研究中心（DCRC）的成像设施内。虽然几个现代荧光显微镜可用于一般用途，我们没有在这个网站的共聚焦显微镜。有很高的要求放在收费服务访问的单一共聚焦显微镜可在这所大学创造短缺的大时间块进行活细胞/组织成像实验所需的。鉴于我们实验的时间敏感性以及将活细胞/组织运送到该位置的困难，在DCRC的成像核心中添加共聚焦显微镜将极大地增强正在进行的NIH资助的研究项目的多样性。如本提案所述，成立了一个咨询委员会，以确定核心用户群，确定DCRC的具体需求，并选择适当的仪器来实现我们研究小组的目标。经过对各种竞争共聚焦系统的广泛咨询和分析，Olympus Fluoview 1000被确定为理想的系统。该系统可以进行修改，将FRET和TIRF功能与膜片钳技术相结合，以满足研究人员的需求，这些研究人员将创新的荧光显微镜和纳米技术方法应用于膜生理学中的中心问题，例如胞吐/胞吞作用，离子通道门控和受体介导的信号转导。此外，该共聚焦系统还将支持第二组研究人员研究谷氨酸和GABA受体的亚细胞定位以及参与血压调节的中央核中神经元模式的产生。建议的共聚焦显微镜的增加不仅将最大限度地提高我们现有的研究计划的影响，而且将有助于招募新的，有才华的教师加入我们机构已经成功的团队。

This subproject is one of many research subprojects utilizing the resources provided by a Shared Instrumentation Grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the grant, which is not necessarily the institution for the investigator. DESCRIPTION (provided by applicant): This proposal requests funds to purchase a laser scanning confocal microscope system with FRET and TIRF microscopic capabilities. The instrument will be housed within the imaging facility of Dalton Cardiovascular Research Center (DCRC) at the University of Missouri. While several modern fluorescent microscopes are available for general use, we do not have a confocal microscope at this site. There is a high demand placed on the fee-for-service access to the single confocal microscope available at this university creating shortage of large time blocks necessary for conducting live cell/tissue imaging experiments. In view of the time- sensitive nature of our experiments and difficulty in transporting live cells/ tissue to this location, the addition of a confocal microscope to the imaging core at DCRC would greatly enhance a diverse array of ongoing NIH-funded research programs. As detailed in this proposal, an advisory committee was formed to identify a core group of users, determine the specific needs of DCRC and to choose the appropriate instrumentation to accomplish the goals of our research groups. Following extensive consultation and analysis of various competing confocal systems, the Olympus Fluoview 1000 has been identified as the ideal system. This system can be modified to integrate FRET and TIRF capabilities with patch-clamp techniques to serve the needs of investigators applying innovative fluorescent microscopy and nanotechnology approaches to central questions in membrane physiology such as exocytosis/ endocytosis, ion channel gating and receptor- mediated signal transduction. In addition, this confocal system will also support a second group of investigators studying subcellular localization of glutamate and GABA receptors and neuronal pattern generation in the central nuclei involved in blood pressure regulation. The addition of the proposed confocal microscope will not only maximize the impact of our existing research programs but also will help in recruiting new, talented faculty to join the already successful group at our Institution.
