DNA and Peptide Facility
Robert Schackmann, Ph.D., Director, bob.schackmann@cores.utah.edu
The DNA and Peptide Facility provides a dependable, rapid, and affordable
supply of synthetic oligonucleotides (DNA and RNA) and peptides, as well
as protein sequencing for researchers at the University of Utah. These resources
are essential tools of modern molecular biology and medicine. Access to
these tools is essential for investigation and diagnosis of genetic alterations
linked to transformed cell states and to many infectious diseases. Oligonucleotides
are used in DNA sequencing, as polymerase chain reaction primers, for site-directed
mutagenesis, and as probes for the identification of genetic information.
Recently, modified oligonucleotides have been employed for anti-sense experiments
with direct therapeutic possibilities. Synthetic peptides are a direct means
of exploring the function of, or to generate immunological agents against,
specific regions of proteins. Protein sequencing is done to confirm the
identity of proteins or to identify regions of amino acid sequence in proteins
of interest.

Biomolecular NMR Core Facility
Jack Shalicky, Ph.D., Director, shalicky@biochem.utah.edu
High-field NMR spectrometers are located in the Chemistry Department and
the Health Sciences Center. Numerous instruments operating at 200 and
300 MHz are available for the routine analysis of synthetic products and
for the structure determination of small molecules. In addition, the Chemistry
Department has three Varian 500 MHz spectrometers, and the Health Sciences
Center has Varian 600 and 500 MHz spectrometers. These high-field instruments
have triple resonance and pulse field gradient capabilities. The instruments
are therefore configured for optimum performance in experiments used to
determine three-dimensional structures of proteins and nucleic acids.
Cesium Irradiation Facility
Raymond L. Warters, Ph.D., Facility Supervisor
The Irradiation Facility provides researchers at the University of Utah with a resource for the irradiation of most types of biological material. The facility includes a J.L. Shepherd and Associates Mark I, Model 30, 6000 Ci 137Cs instrument, which permits irradiation of large samples such a multiple mice at a dosage rate as low as
0.5 Gy min-1; small samples, such as cells or macromolecules in solution, can be treated at a dosage rate as high as 37 Gy min-1. Thus the irradiator has a wide range of potential research applications.
Mass Spectrometry Facility
Chad Nelson, Ph.D., Director, cnelson@genetics.utah.edu
Mass spectrometers are located in the departments of Chemistry and Medicinal
Chemistry. Routine samples are run by facilities in both departments offering
EI, CI, fast atom bombardment, electrospray ionization, MALDI, tandem
MS, LC/MS and GC/MS services. Advanced instrumentation available for research
in mass spectrometry includes five computer-controlled mass spectrometers
in the department of Medicinal Chemistry which possesses an unusually
diverse range of capabilities for studies of biological molecules; these
include electrospray ionization, tandem mass spectrometry (MS/MS) and
electrospray liquid chromatography-mass spectrometry (LC/MS) and matrix-assisted
laser desorption ionization (MALDI) instruments.
Cell Fluorescent Imaging Facility
Chris Rodesch, Ph.D., Director, crodesch@cores.utah.edu
The Cell Imaging Facility provides university and external researchers
with state-of-the-art resources both for analysis of low-level fluorescent
probes in living and fixed samples and for cell microinjection. Instrumentation
provided by the Facility includes: 1. an array of conventional and confocal
microscopes, each provided with stage adaptors for use with live cell
cultures and coupled to sophisticated image acquisition hardware and software;
2. two automated cell microinjection units for cytoplasmic and nuclear
introduction of dissolved substances into living cells; and 3. workstations
for processing, analysis, and editing of still image and video data generated
using either facility or external instrumentation. Sophisticated image
acquisition and analysis regimes are possible, including time lapse, z-series,
ratiometric analysis, and deconvolution, and customized automations can
be developed to suit experimental requirements. Experimental design consultation
and training for use of all instrumentation and software are available,
and the Facility is open at all hours to users trained in instrument operation.

The facility includes a micro-injection/surgery room, pathogen-free animal
rooms, a tissue culture facility, and a molecular biology laboratory.
The core offers technical assistance for blastocyst injection procedures
and maintains all transgenic mouse colonies in an isolated section of
the vivarium dedicated for this purpose. The core maintains a full complement
of genomic libraries, selectable markers, and bacterial and phage vectors
required for gene modification in mouse embryonic stem cells, and other
rodent and human cultured cell lines.
Protein Interaction Facility
David Myszka, Ph.D., Director, dmyszka@cores.utah.edu
The Protein Interaction Facility provides investigators with easy access
to advanced technologies used in characterizing binding interactions.
Currently, a BIACORE 2000 optical biosensor is used to define the assembly
state, affinity, and kinetics of an interaction. The advantage of optical
biosensors is that they allow the real-time analysis of molecular interactions
without labeling requirements. This makes the technology applicable to
the study of a wide variety of biological molecules including proteins,
oligonucleotides, oligosaccarides and lipids.
Electron Microscopy Facility

This facility provides a variety of state-of-the-art microscopy services
to the basic science and clinical communities. The microscopy services
provide investigators with a variety of light and electron microscopy
capabilities, as well as image analysis (quantitative morphology). Technical
services offered by the core include, light microscopy (brightfield, fluorescence,
3-D, etc.), transmission and scanning electron microscopy, histochemistry,
immunohistochemistry, in situ hybridization, laser capture microscopy,
PCR, RT-PCR, in situ PCR/RT.PCR, and image analysis.
Microarray Facility
Brian Dalley, Director, brian.dalley@hci.utah.edu
The Microarray Core Facility provides Huntsman Cancer Institute researchers
with a highly sensitive and comprehensive tool to discover differentially
regulated genes. Microarray analysis can serve a very broad spectrum of
biologic applications ranging from gene regulatory effects of artificially
introduced gene alterations and pharmacological responses in cultured
cells to genetic profiling of surgically removed human tumor specimens.
Using our Gen3 Microarray Spotter allows us to analyze 4608 unique cDNA
clones spotted in duplicate per slide. Our goal is to provide HCI investigators
with sensitive and timely microarray comparisons of biologic samples related
to cancer research. In addition to the Microarray Spotting and Scanning
Instruments, the most critical resource for performing comprehensive microarray
analysis is our expanding inventory of unique human cDNA clones. Currently
our inventory holds more than 23,700 clones, representing approximately
18,000 unique genes.
