The Electron Microscopy Laboratory offers the tools and technical expertise for research and training in microscopy with both light and electron microscopes. We maintain and operate electron microscopes (TEM and SEM with EDS), a confocal laser scanning microscope, and the ancillary equipment needed for the preparation of specimens for EM and other microscopy. Our multiple light microscopes encompass optics for bright-field, phase-contrast, differential-interference, and fluorescence imaging. Technical Services: • Microscope operation—full operation of all electron and light microscopes.

Established through a COBRE Grant from NIH, the COBRE Microscopy and Image Analysis CORE has two specific aims designed to provide training and access to (1) state-of-the art, high resolution live imaging services and (2) experiment planning, data management and image analysis services. The Microscopy and Image Analysis Core (MIAC) offers cutting-edge imaging capabilities with its Zeiss LSM980 equipped with AiryScan 2. This advanced microscope supports a wide array of applications, including multi-color experiments, live sample imaging, protein colocalization, tiling of large samples, Z-stack 3D/4D imaging, and weak label detection. Additionally, MIAC provides expert guidance in microscopy and image analysis, as well as comprehensive training and support to advance research across various model organisms. For image analysis, the facility is equipped with Imaris software on a high-performance workstation, ensuring robust and sophisticated data analysis. |
