Core Facilities & Resources

The Philadelphia campus of Penn Vet includes the School's oldest and newest buildings; from the Vernon and Shirley Hill Pavilion, which opened in November of 2006, to the Old Vet Quadrangle Building, built in 1912, our buildings reflect our tradition of excellence and our connection to the future of veterinary medicine.

Our research facilities include state-of-the-art laboratories on both Philadelphia and Kennett Square campuses.

PennVet Imaging Core

 The Penn Vet Imaging Core (PVIC) was established to provide access to cutting-edge optical imaging capabilities for the University of Pennsylvania, Children's Hospital, and Wistar Institute biological and biomedical research communities. The PVIC includes three confocal microscopes and a widefield TIRF microscope, each of which is configured for intravital, live cell and fixed specimen imaging. The Core Director and Manager have over 50 years of combined imaging experience and are focused on making this technology accessible to all labs, regardless of prior level of experience.



  • Leica SP5 upright multiphoton system

  • Leica SP5-2 inverted confocal FLIM/FRET system

  • Leica DMI400 with Yokagawa spinning disk confocal system

  • Leica DMI6000 with total internal reflection fluorescence (TIRF) capability

  • Nikon E600 widefield fluorescence upright microscope with camera

Image Analysis

  • Access to and training on Volocity and MetaMorph image analysis software is available, as is remote access to Volocity.

Penn Vet Imaging Core Training

The PVIC provides free training, advice, and hands-on assistance to all core users. For training, consultation, and access, contact:

Core Manager

  • Gordon Ruthel, PhD
  • Dr. Ruthel has more than 25 years of advanced imaging experience. Prior to joining PVIC, Dr. Ruthel ran an imaging core facility for USAMRIID at Fort Detrick.
  • Phone: 215-746-0471
    Email: goruthel@vet.upenn.edu

Core Director

  • Bruce Freedman, VMD, PhD
  • Dr. Freedman has more than 30 years experience using advanced optical imaging techniques in his research. He has served as PVIC Director since the Core's inception in 2008.
  • Phone: 215-573-8212
    Email: bruce@vet.upenn.edu



These instruments and the core provide capability and support for imaging structures in fixed specimens as well as dynamic events in living cells and thick tissues. The Department of Pathobiology maintains this facility and oversees the fee structure for this service center.

Flow Cytometry Satellite

The flow cytometry core housing our two units will be located on the third floor of the Hill Pavilion and jointly managed under the School of Medicine Flow Cytometry and Cell Sorting Resource Laboratory (FCCSRL).

SVM units

  • A BD FACS Canto was recently installed: FACSCanto II Flow Cytometry System is capable of detecting 6 fluorescence colors with dual laser (488nm and 633nm) excitation. The BD FACSCanto II boasts a new fluidic and optical design, which allows for high acquisition speed and low sample carryover. Fully digital electronics make for easier multicolor compensation.
  • The BD FACSCalibur is a two-laser (488nm and 635nm), four-color analog analyzer.

Please visit www.med.upenn.edu/bmcrc for information on rates, all locations and training, or call the core lab at 215.898.3528. Training is required before using the facility.

To further inquire about the services offered, training, and the fee structure by the FCCSRL, contact the Technical Director, Hank Pletcher, at 215.898.3528.
