DESCRIPTION (provided by applicant): This R24 Grant is submitted to establish a state-of-the-art Confocal Laser Scanning Microscope Core Facility for vision researchers at Thomas Jefferson University (TJU). It will provide a well-established group of NEI-funded vision researchers at TJU the means to perform cutting edge fluorescence microscopy analysis of both fixed and live cells and tissues, greatly enhancing their vision research programs. This facility will also serve collaborators and colleagues of the NEI-funded investigators who have an interest in vision biology. It is hoped that the advanced technology offered by this facility will attract additional investigators at TJU to apply their knowledge to questions in vision research, either independently or in collaboration with the core group of investigators. The confocal microscope we propose to purchase, the Zeiss LSM 510 META, well addresses the needs of the vision investigators at TJU to examine the complex and dynamic relationships between proteins at the cellular, subcellular and molecular level. It offers the unique capability of emission fingerprinting which can separate up to 8 different fluorescent markers despite overlap of their emission spectra, thereby permitting analysis of the molecular relationships of distinct cellular components. This microscope makes it simple to perform dynamic FRAP, FLIP and FRET analyses. It can resolve rapid cellular processes and allows for quantitative analysis of image series. It is expected that this confocal facility not only will enhance the current research goals of this group of vision researchers but also provide new avenues for their research projects not before possible. Access to this confocal microscope should allow this dynamic group of vision researchers, who have already provided many important contributions to their specific fields, to both enhance and expand their research directions and to increase their productivity, without technology being a limitation. It is our long term goal, as we reach the required nucleus of NEI-funded investigators, to expand this facility into a larger Core Facility for vision researchers at TJU and Wills Eye Hospital. We envision this core as providing not only additional technologies that will enhance the research activity of these investigators, but also to provide a central site that will foster intellectual interactions between the investigators and lead to even greater cooperation and collaboration within the TJU vision community.

描述（由申请人提供）：本R24拨款旨在为托马斯杰斐逊大学（TJU）的视觉研究人员建立最先进的共聚焦激光扫描显微镜核心设施。它将为TJU的一组由nei资助的视觉研究人员提供对固定和活细胞和组织进行尖端荧光显微镜分析的手段，大大加强他们的视觉研究项目。该设施还将为nei资助的对视觉生物学感兴趣的研究人员的合作者和同事提供服务。希望该设施提供的先进技术能够吸引更多的TJU研究人员将他们的知识应用于视觉研究中的问题，无论是独立的还是与核心研究小组合作的。我们建议购买的共聚焦显微镜，蔡司LSM 510 META，很好地满足了TJU视觉研究人员在细胞，亚细胞和分子水平上研究蛋白质之间复杂和动态关系的需求。它提供了独特的发射指纹识别能力，可以分离多达8种不同的荧光标记，尽管它们的发射光谱重叠，从而允许分析不同细胞成分的分子关系。该显微镜使其易于执行动态FRAP， FLIP和FRET分析。它可以解决快速细胞过程，并允许定量分析的图像系列。期望这台共聚焦设备不仅能提高这组视觉研究者目前的研究目标，还能为他们的研究项目提供新的途径。使用这台共聚焦显微镜将使这群已经在各自领域做出了许多重要贡献的动态视觉研究人员能够加强和扩展他们的研究方向，并提高他们的生产力，而不受技术的限制。这是我们的长期目标，因为我们达到了所需的nei资助的研究人员的核心，将这个设施扩展成一个更大的核心设施，为TJU和威尔斯眼科医院的视觉研究人员服务。我们设想这个核心不仅可以提供额外的技术，以提高这些研究人员的研究活动，而且还可以提供一个中心站点，促进研究人员之间的智力互动，并在TJU愿景社区内带来更大的合作和协作。
