DESCRIPTION (provided by applicant): The detection and imaging of molecules in biological systems is a vitally important tool in biomedical research. Conventional fluorescence microscopy is an extremely useful technique, but is limited by the loss of resolution caused by emission from sources outside of the focal plane. Confocal Laser Scanning Microscopy circumvents this problem by scanning the specimen with light from a laser-illuminated pinhole and imaging the emitted light through a detector pinhole. All out-of-focus fluorescence is rejected by the pinhole, resulting in submicron resolution in the X, Y, and Z axes. In 1998, Dr. Kent Keyser was the recipient of an NIH NCRR Shared Instrument Grant, a UAB Health Services Foundation award, and start-up funds from the UAB Office of the Provost, the Chairs of Departments in both the Medical and Academic Divisions of UAB, and Center Directors. These funds were used to establish a new facility, the High Resolution Imaging Facility. This imaging resource is equipped with a Leica Confocal Imaging Spectrophotometer TCS SP unit. It is configured for multiphoton excitation with a Coherent MIRA Ti:Sa ultrafast laser with output selectable between 690-990 nanometers. This permits imaging of living cells and tissues with minimal phototoxicity, and of structures 200-400 micrometers from the tissue surface. The SP allows user selection of specific portions of the emission spectrum to be delivered to the detector. The result is higher fluorescence yield, reduced crosstalk, and improved image quality. The Facility also includes an Olympus Fluoview CLSM with fiber launched Krypton ion and Argon ion lasers, conventional fluorescence and DIG microscopy equipment, and work stations equipped with digital deconvolution software, output and image storage devices. Through a cooperative agreement with the Birmingham Veteran's Administration Medical Center, Cancer Center members have access to a Leica TCS SP unit equipped with a UV laser and UV corrected optics. The Leica instruments are equipped with either three or four detector channels, a transmitted light channel, and Argon ion, Krypton ion and Helium:Neon lasers, and are able to image up to three fluorophores simultaneously. In a cooperative agreement with the Cell Adhesion and Matrix research center, and the Vision Science Research Center, the HRIF now offers access to a state of the art FRET system. The Facility offers Comprehensive Cancer Center members access to a comprehensive imaging facility with a full range of instrumentation and the expertise to use these resources productively.

描述（由申请人提供）：生物样品中分子的检测和成像 系统是生物医学研究中极其重要的工具。 传统的荧光显微镜是一种非常有用的技术，但受到焦平面外光源发射造成的分辨率损失的限制。 共聚焦激光扫描显微镜通过从激光照射的针孔用光扫描样品并通过检测器针孔成像发射的光来规避这个问题。 所有散焦荧光都被针孔拒绝，从而在X、Y和Z轴上实现亚微米分辨率。 1998年，肯特凯瑟博士获得了美国国立卫生研究院NCRR共享仪器补助金、UAB卫生服务基金会奖，以及来自UAB教务长办公室、UAB医学和学术部门主任和中心主任的启动资金。 这些资金用于建立一个新的设施，即高分辨率成像设施。 此图像资源是 配备Leica共焦成像分光光度计TCS SP单元。 其被配置用于 使用相干MIRA Ti：Sa超快激光器进行多光子激发，输出可在690-990纳米之间选择。 这允许以最小的光毒性对活细胞和组织进行成像，以及对距离组织表面200-400微米的结构进行成像。 SP允许用户选择要传送到检测器的发射光谱的特定部分。 其结果是更高的荧光产率，减少串扰，并提高图像质量。 该设施还包括一台奥林巴斯Fluoview CLSM，配备光纤发射氪离子和氩离子激光器，传统荧光和DIG显微镜设备，以及配备数字解卷积软件、输出和图像存储设备的工作站。 通过与伯明翰退伍军人管理局医疗中心的合作协议，癌症中心的成员可以使用配备紫外激光器和紫外校正光学器件的Leica TCS SP设备。 徕卡仪器配备有三个或四个检测器通道、一个透射光通道以及氩离子、氪离子和氦：氖激光器，能够同时对多达三种荧光团成像。 在与细胞粘附和基质研究中心以及视觉科学研究中心的合作协议中，HRIF现在提供最先进的FRET系统。 该设施提供综合癌症中心成员 获得一个全面的成像设施与全方位的仪器和专业知识，以有效地利用这些资源。
