The WCM CLC Imaging Core Facility provides state-of-the-art instruments and services, and expertise in their applications, to the Weill Cornell Medicine (WCM) community and to outside investigators. Resources and services include confocal microscopy, wide field fluorescence microscopy, multiphoton microscopy, automated optical microscopy, electron microscopy, histology services (paraffin and cryo sample preparation), phosphorimaging, and X-ray film processing. The facility provides consultation on project design and image visualization and analysis, and offers seminars, training and educational workshops.
History: The WCM CLC Microscopy and Imaging Core Facility is the result of consolidation of five previously separate core facilities: Optical Microscopy, Multiphoton Microscopy, Electron Microscopy and Histology, Cell Screening, and X-ray Processing and Phosphorimaging Cores. These resources are now offered as coordinated services by an integrated core facility.
Location: The core is located on the 1st and 2nd floor of the “A” building and X ray and phosophorimaging is in the basement of the "A" building at 1300 York Avenue, New York, NY. There is also a location on the 9th floor of the Belfer Research Building, 413 East 69th Street, New York, NY.
WCM Core Laboratories Center (CLC): The WCM CLC was established in 2015. The CLC includes core facilities that offer resources and services in genomics and epigenomics, proteomics and metabolomics, flow cytometry, imaging (e.g., optical and electron microscopy, high content screening, MRI, PET/CT, and ultrasound), synthetic and analytical chemistry, and nuclear magnetic resonance (NMR).
Open to all: The resources and services of the core facility are open to all investigators at Weill Cornell Medicine, Cornell University and Cornell-affiliated institutions. The facility also provides services to external investigators at both academic institutions and commercial enterprises.
Confocal Microscopy: Zeiss LSM 880, Zeiss LSM 880 + AiryScan, and LeicaSP5. Features include: multiple wavelength imaging of thick samples; imaging of fixed and live cells, tissue, and 3D cultures; super-resolution (32-element Airyscan detector); spectral imaging (32-channel GaAsP array); “filterless” acquisition (custom emission bandwidths); tile scanning; complex time lapse experiments. Laser excitations: 405, 458, 488, 514, 561, 594, 633 nm. Objectives: 10x, 25x, 40x, 63x, 100x (all but 10x are oil immersion; all DIC for simultaneous transmitted light imaging).
