DESCRIPTION (provided by applicant): Funds are requested to acquire a Zeiss Cell Observer SD (spinning disc) confocal microscope to support the research efforts of multiple NIH-funded investigators at Virginia Commonwealth University (VCU). This live cell / live tissue imaging system is to be housed in a well-established, well-used and highly productive microscopy shared resource facility in the School of Medicine at VCU. The VCU Microscopy Facility is available to all VCU investigators and serves diverse research programs. The facility is directed by the PI, who has expertise in multiple aspects of microscopic imaging. Staff is available for consultation, instruction, assistance and collaboration. The requested equipment will help meet increasing research demands that cannot be fulfilled by the existing equipment in the Facility; namely, the ability to collect high resolution, high contrast confocal images at rapid image acquisition rates. Many research questions have been developed that require a higher temporal resolution and cannot be answered the relatively slow laser-scanning (point scanning) confocal systems that are presently in the facility. The requested Zeiss Cell Observer SD spinning disc confocal microscope is configured around an AxioObserver Z1 inverted stand and equipped with a Yokogawa CSU-X1A spinning disc unit, a Photometrics QuantEM 512SC cooled CCD camera (for high speed, high sensitivity imaging), an AxioCam MRm (for high resolution imaging), a high resolution piezo driven Z stage (for rapid 3D data collection) and a stage incubation system (to support live cell / live tissue imaging). This instrument will be used to image a variety of sample types including cells in culture, acute tissue slices, organotypic slice cultures and organisms (e.g. zebra fish). During the past year (2008), 83 different labs, representing 222 investigators from 23 different departments at VCU have used the Microscopy Facility and its services (widefield fluorescence, confocal, multi-photon, TIRF, atomic force/scanning probe, transmission & scanning electron microscopy, image analysis and sample preparation). During 2008, the laser scanning confocal microscope was used by 104 users from 49 labs, representing 17 departments. The projects conducted by these researchers represent a broad range of studies (cell biology, microbiology, neurobiology, bioengineering, virology, pharmacology, physiology, etc.). Representative studies of major users (from 9 labs; 5 departments) have been highlighted in this proposal. Included are research reports from current users of the Microscopy Facility (Akbarali, Fuss, Hauser, Knapp, Povlishock, Ratz) as well as from 3 other investigators (Block, Lister, Tombes) who require the requested instrumentation to advance their research programs. The acquisition of a rapid imaging live cell confocal system will have a major impact on research at VCU as it will enhance the research capability and productivity of a well used core facility and will attract additional users (whose needs currently cannot be met by the available equipment).

描述（由申请人提供）：资金要求获得蔡司细胞观察SD（旋转盘）共聚焦显微镜，以支持多个NIH资助的研究人员在弗吉尼亚联邦大学（VCU）的研究工作。这种活细胞/活组织成像系统将被安置在VCU医学院的一个完善的，使用良好的和高效的显微镜共享资源设施中。VCU显微镜设施可供所有VCU研究人员使用，并为各种研究项目提供服务。该设施由PI指导，PI在显微成像的多个方面具有专业知识。工作人员可提供咨询、指导、援助和合作。所要求的设备将有助于满足该设施现有设备无法满足的日益增加的研究需求，即能够以快速的图像采集速度收集高分辨率、高对比度的共焦图像。许多研究问题已经开发，需要更高的时间分辨率，不能回答相对较慢的激光扫描（点扫描）共焦系统，目前在设施。所要求的Zeiss Cell Observer SD旋转圆盘共聚焦显微镜配置在AxioObserver Z1倒置支架周围，并配备Yokogawa CSU-X1 A旋转圆盘装置、Photometrics QuantEM 512 SC冷却CCD相机（用于高速、高灵敏度成像），AxioCam MRm在一个实施例中，该系统包括一个高分辨率的Z台（用于高分辨率成像）、一个高分辨率的压电驱动Z台（用于快速3D数据收集）和一个台孵育系统（用于支持活细胞/活组织成像）。该仪器将用于对各种样品类型进行成像，包括培养细胞、急性组织切片、器官型切片培养物和生物体（例如斑马鱼）。 在过去的一年（2008年）中，代表VCU 23个不同部门的222名研究人员的83个不同实验室使用了显微镜设施及其服务（宽场荧光、共聚焦、多光子、TIRF、原子力/扫描探针、透射和扫描电子显微镜、图像分析和样品制备）。在2008年期间，激光扫描共聚焦显微镜被来自49个实验室，代表17个部门的104名用户使用。这些研究人员进行的项目代表了广泛的研究（细胞生物学，微生物学，神经生物学，生物工程，病毒学，药理学，生理学等）。 主要用户的代表性研究（来自9个实验室; 5个部门）已在本提案中突出显示。包括来自显微镜设备当前用户（Akbarali、Fuss、豪瑟、克纳普、Povlishock、Ratz）以及其他3名需要所需仪器以推进其研究计划的研究者（Block、Lister、Tombes）的研究报告。 获得快速成像活细胞共聚焦系统将对VCU的研究产生重大影响，因为它将提高研究能力和使用良好的核心设施的生产力，并将吸引更多的用户（现有设备目前无法满足其需求）。
