The Plant Imaging Center (PIC) is a multi-user research center in the Department of Botany offering expertise, instruction, and instrumentation in modern microscopy to the plant research community at the University of Wisconsin - Madison. Current research in the PIC covers a broad range of plant biology topics including calcium signaling, tropism responses, mechanical signaling, embryo development, leaf development, hormone signaling, pollen phenotyping, protein degradation, and membrane dynamics.
Synchrotron technology allows researchers to utilize light as a tool. At SRC, light is produced by hurtling electrons at near the speed of light around a circular track--which, at SRC, is appropriately called Aladdin. Those electrons are manipulated in such a way that light, ranging SRC Vaultfrom infrared to x-ray, is produced.
Medical School Electron Microscopy Facility (in Bardeen Labs)
The Medical School Electron Microscope Facility is an internal service facility committed to providing a top-quality and up-to-date electron microscopy services to the University of Wisconsin system. The Facility is open for use to the University research community, as well as the private sector (at an additional cost). We will work with any organization needing electron microscopy applications, consultation, and/or training.
The Biophysics Instrumentation Facility (BIF) serves researchers at the University of Wisconsin-Madison. The fourteen state-of-the-art instruments in the BIF have a common purpose: Each enables users to study the conformation, structure, or complexation of biological and other macromolecules. These interrelated properties are the basis for biological and macromolecular function. Each of the instruments provides distinct information, and the ensemble enables thorough characterization of conformation, structure, and complexation.

This laboratory has existed and provided services to McArdle investigators and other Medical School staff for 30 years. Dr. Henry C. Pitot has been and continues to be the faculty advisor for this facility.
With an emphasis on cancer research, the Wisconsin Institutes for Medical Research (WIMR) at the University of Wisconsin School of Medicine and Public Health in Madison is designed to allow researchers to work with scientists from other disciplines, speeding the transfer of science to the people who will benefit from it.
Wisconsin Veterinary Diagnostic Laboratory (WVDL)
The Wisconsin Veterinary Diagnostic Laboratory, with facilities located in Madison and Barron, is a full service laboratory serving veterinarians from Wisconsin and throughout the United States.
WVDL is accredited by the American Association of Veterinary Laboratory Diagnosticians and provides a broad range of diagnostic services to the production, companion, and exotic animal industries. WVDL performs surveillance tests for a variety of animal diseases (e.g., brucellosis) and performs tests to qualify animals, semen, and embryos for interstate and international shipment.
The Materials Science Center (MSC) provides instrumentation and expertise for the characterization of materials and nanostructures. It houses four scanning electron microscopes and three transmission electron microscopes, multiple x-ray diffractometers, two surface analysis instruments, and an atomic force microscope. Recent acquisitions include a dual-beam focused ion beam instrument, a scanning confocal micro-Raman spectrometer, and a small-angle x-ray diffractometer.
The William S. Middleton Memorial Veterans Hospital is a highly affiliated acute care facility providing comprehensive tertiary care in medicine, surgery, neurology, and psychiatry. Approximately 1,400 professional, administrative, and support personnel provide the widest range of services to the more than 34,000 veterans treated annually, either as inpatients or outpatients.
National Magnetic Resonance Facility at Madison (NMRFAM)
NIH-funded, shared instrumentation laboratory located in the Biochemistry Department and directed by Professor John Markley. NMRFAM contains nine modern multinuclear NMR spectrometers with field strengths between 400 MHz and 900 MHz equipped for the most demanding multidimensional, multinuclear spectroscopic applications. Cryogenically cooled probes are installed on five of the instruments.

3-D reconstruction of rat lung alveolus perfused with a synthetic hemoglobin solution (red) under conditions of high inflation pressure . Such pressures exclude red cells from alveoli, but the acellular solution nearly fills the alveolus shown. These solutions could improve oxygenation in trauma patients, for whom high lung inflation pressures are a necessity. (The image was modified using VoxBlast (Vaytek, Inc.). Robert Conhaim, 1999
