DESCRIPTION (provided by applicant): Funds are requested to purchase a Zeiss LSM 510 laser-scanning confocal microscope for integration into the Genetics Training Program (GTP) Imaging Facility. The University of Wisconsin GTP encompasses more than 75 faculty trainers in 10 departments and 3 colleges. It is recognized as one of the premier programs worldwide for research and training in Genetics. To maintain and advance our leadership in this field and to continue to train the most promising scientists, it is essential to have access to the state-of-the-art instruments and facilities on which our research depends. A confocal microscope has become one of the most essential research tools in modern biology, regardless of the particular experimental organism or particular problem under investigation. However, we currently lack consistent, affordable access to a confocal microscope. To fill this need, we are applying here for funds to purchase a confocal microscope. Eight primary users who will manage and subsidize maintenance of the microscope are submitting this application on behalf of the entire GTP. With reliable access to a confocal microscope, GTP scientists will be able to (i) simultaneously observe the cellular and sub-cellular localization of three different molecules (ii) follow the in vivo expression and localization dynamics of multiple proteins; (iii) visualize thin optical sections of thick biological specimens; and (iv) obtain high-resolution 3-D reconstructions of their specimens. The addition of a confocal microscope to our imaging facility will have a major impact on the research programs of each of the primary users. These programs range from studies of yeast to mice, and address fundamental questions in biology from the regulation of gene expression to the molecular mechanisms of cell division, from embryonic and organ development to neural signaling and memory formation. Relevance: The ongoing studies of the primary users are yielding important insights into the biological processes underlying human disorders including cancer, birth defects, mental retardation, deafness, blindness, and neurodegeneration, among others. We also will attract new users from within the GTP, so an accessible confocal will broaden and strengthen the research programs of laboratories beyond those of the initial primary users. All of the GTP faculty are engaged in research of significant relevance to human health; most have current funding through NIH.

描述(由申请者提供)：需要资金购买蔡司LSM 510激光扫描共聚焦显微镜，以便整合到遗传学培训计划(GTP)成像设施中。威斯康星大学GTP拥有超过75名教员，分布在10个系和3个学院。它被公认为是全球遗传学研究和培训的主要项目之一。为了保持和推进我们在这一领域的领导地位，并继续培养最有前途的科学家，有必要获得我们的研究所依赖的最先进的仪器和设施。共焦显微镜已经成为现代生物学中最重要的研究工具之一，无论是哪种特定的实验生物体或正在研究的特定问题。然而，我们目前缺乏一致的、负担得起的共焦显微镜。为了满足这一需求，我们正在申请购买共焦显微镜的资金。将管理和资助显微镜维护的八名主要用户代表整个GTP提交了这份申请。通过可靠地使用共焦显微镜，GTP科学家将能够(I)同时观察三种不同分子的细胞和亚细胞定位；(Ii)跟踪多种蛋白质的体内表达和定位动态；(Iii)可视化厚生物标本的薄光学切片；以及(Iv)获得其标本的高分辨率3-D重建。在我们的成像设备中增加一个共焦显微镜将对每个主要用户的研究计划产生重大影响。这些计划的范围从酵母研究到小鼠，并解决了生物学中的基本问题，从基因表达的调节到细胞分裂的分子机制，从胚胎和器官发育到神经信号和记忆的形成。相关性：主要使用者正在进行的研究正在产生对人类疾病潜在的生物学过程的重要见解，包括癌症、出生缺陷、智力低下、耳聋、失明和神经退化等。我们还将从GTP内部吸引新的用户，因此可访问的共焦将拓宽和加强实验室的研究计划，而不是最初的主要用户。GTP的所有教职员工都从事与人类健康密切相关的研究；大多数人目前通过NIH获得资金。
