DESCRIPTION (provided by applicant): This proposal is to obtain a new commercial Zeiss ELYRA S.1 Super-Resolution Structured Illumination Microscope (SR-SIM) that has unique multi-channel super- resolution capabilities for a group of cell biologists studying the molecular architecture of processes including cell division, migration, polarity and organelle dynamics and inheritance. One of the major limitations of light microscopy for the study of cell structure and function has been the inability to resolve structures below the diffraction limit imposed on optica systems. The ELYRA S.1 SR-SIM uses structured illumination to generate images that exceed the normal resolution barrier by two-fold in both lateral (X, Y) and axial (Z) directions. The ELYRA S.1 SR-SIM provides a rare combination that is not found in other commercially available SR-SIMs: superior performance (user- friendly high-resolution 3D SIM imaging in three channels, and rapid live-cell SIM imaging) and low cost. The major users of the requested instrument are all experienced cell biologists who have made extensive use of light microscopic approaches in their past work. This group seeks to use the ELYRA S.1 SR-SIM to extend their NIH-funded studies to obtain higher-resolution information on processes such as the interaction of cytoskeleton with membranes, organelle genome structure and localization, kinetochore dynamics, and nuclear envelope structure. Collaborative interactions already exist within members of this group and this is expected to facilitate adoption of procedures and techniques that will enhance the utility of the super-resolution microscope. The instrument will be administered as part of an established and well-supported imaging center at Columbia University, which will facilitate broad exposure of the instrument to additional users. The higher-resolution information obtained with the ELYRA S.1 SR- SIM should extend our knowledge of fundamental cellular processes occurring below the resolution of our existing light microscopes. This information will be helpful in identifying new avenues for the development of therapeutic approaches for the treatment of diseases such as cancer, inflammation and heart disease that result in part from deficits in the proper organization of cellular architecture.

描述(由申请人提供)：本提案旨在获得一种新型商用蔡司ELYRA S.1超分辨率结构照明显微镜(SR-SIM)，该显微镜具有独特的多通道超分辨率能力，可供一群细胞生物学家研究包括细胞分裂、迁移、极性和细胞器动力学和遗传在内的过程的分子结构。光学显微镜研究细胞结构和功能的主要局限性之一是无法分辨光学系统上的衍射极限以下的结构。ELYRA S.1 SR-SIM使用结构照明来生成在横向(X，Y)和轴向(Z)方向都超出正常分辨率障碍两倍的图像。ELYRA S.1 SR-SIM提供了其他商业SR-SIM所没有的罕见组合：卓越的性能(用户友好的三个通道的高分辨率3D SIM成像，以及快速的活细胞SIM成像)和低成本。所要求的仪器的主要用户都是经验丰富的细胞生物学家，他们在过去的工作中广泛使用了光学显微镜方法。该小组试图使用ELYRA S.1 SR-SIM来扩展他们由NIH资助的研究，以获得关于细胞骨架与膜的相互作用、细胞器基因组结构和定位、动粒动力学和核膜结构等过程的更高分辨率的信息。这个小组的成员中已经存在协作互动，预计这将促进采用将增强超分辨率显微镜实用价值的程序和技术。该仪器将作为哥伦比亚大学一个成熟且得到良好支持的成像中心的一部分进行管理，这将促进该仪器向更多用户广泛展示。使用ELYRA S.1 SR-SIM获得的更高分辨率的信息应该会扩展我们对发生在现有光学显微镜分辨率下的基本细胞过程的知识。这些信息将有助于确定开发治疗癌症、炎症和心脏病等疾病的治疗方法的新途径，这些疾病的部分原因是细胞结构的适当组织存在缺陷。
