LOCATION

MIR Preclinical Services is conveniently located in the center of Michigan's biotechnology corridor, near the University of Michigan's Hospital/Medical Research facilities and 40 minutes from Detroit Metro Airport. This 20,000 square foot facility houses a 8,000 square foot vivarium, imaging suites, tissue culture facility, molecular biology/chemistry laboratory and administrative offices. This state-of- the-art facility was specially designed to meet MIR's and the needs of its clients.

MIR Preclinical Services (MIR) is a contract research organizatior (CRO) that specializes in the preclinical assessments of novel anti-cancer and anti-inflammatory therapeutic agents.  The company has vast experience in cancer with Xenograft, sygeneic, and transgenic animal models of cancer.  MIR employs a wide array of novel imaging technologies including preclinical MRI, preclinical CT, preclinical PET and biophotonic imaging.  This is a picture of the company located at 800 Technology Drive, Ann Arbor, MI 48108
IMAGING EQUIPMENT
MIR's preclinical magnetic resonance imaging (MRI) equipment is specifically designed for small animal MRI studies.  This 7 Tesla MRI system is ideal for anatomical and functional imaging and includes T1 and T2 weighted imaging, diffusion MRI, contrast enhanced imaging , dynamic contrast enhanced (DCE) imaging, in vitro MRI and chemical shift analysis.
Varian 7 Tesla MRI

MIR Preclinical Services owns and operates, on site, a 7 Tesla Varian small animal MRI system with a 12 cm imaging bore. The 7 Tesla field strength offers optimal signal to noise ratios and image quality for imaging in vivo tumor models, without the complications that higher fields can present. MIR's imaging staff has optimized animal throughput for a variety of in vivo imaging protocols through innovative animal preparation techniques and implementation of software to facilitate image acquisition and post-processing. MIR optimizes imaging throughput to offer the best value to its clients.

   
MIR's preclinical positron emission tomography (PET) equipment is specifically designed for small animal studies.  This system also has a preclinical computed tomography (CT) system on the same gantry and can overlay PET images onto the CT image, yielding a co registered image.  MIR routinely run PET studies with 18FDG: 18-fluoro-deoxyglucose, a biomarker for metabolism and 18FLT: 18-fluoro-thymidine, a biomarker for cell proliferation.

MIR Preclinical Services owns and operates, on site, a high resolution (spatial resolution below 2.0 mm) preclinical PET with Co-Registered CT on the same gantry. This system has the highest sensitivity and largest axial field of view among small animal PET systems, increasing throughput and minimizing costs. The CT system can performn whole body image acquisitions that take less than a minute, to very-high-resolution (43 µm) whole body scans.

Preclinical Gamma Medica PET with Co-Registered CT
   

MIR's preclinical positron emission tomography (PET) equipment is specifically designed for small animal studies.  This system also has a preclinical computed tomography (CT) system on the same gantry and can overlay PET images onto the CT image, yielding a co registered image.  MIR routinely run PET studies with 18FDG: 18-fluoro-deoxyglucose, a biomarker for metabolism and 18FLT: 18-fluoro-thymidine, a biomarker for cell proliferation.

Preclinical Siemens PET

MIR Preclinical Services owns and operates, on site, a second high resolution preclinical PET system. This Siemens R4 is a dedicated PET scanner with 6,000 detectors (spatial resolution of 2.0 mm) and a 13cm bore. The system has a 7.8 cm field of view with single scan slice of about 1mm thickness.
   
MIR Preclinical Services offers biophotonic imaging with its Xenogen IVIS preclinical bioluminescence and fluorescence imaging system.  This system is well suited for tracking metastatic tumors (human tumor xenografts expressing a bioluminescence reporter gene) in real time, non-invasively, in vivo.  MIR also has a number of proprietary molecular reporters that indicate drug induced effects at the molecular level .

MIR Preclinical Services owns and operates, on site, a Xenogen IVIS® Imaging System. This system is physically calibrated and measures actual light photons emitted from the source. This system has a heated base to stabilize kinetic reactions which may create data artifacts. This system also has Xenogen's XFO-12 Fluorescence Option which provides the option of fluorescent imaging in addition to bioluminescent imaging for both in vivo and in vitro applications. The following table shows the fluorescence wavelengths which the system can accommodate.

Xenogen's IVIS Imaging System with XFO-12 Fluorescence Option
   
MIR Preclinical Services offers preclinical computed tomography (CT) imaging with its GE RS150 system.  This was a prototype system and only 2 were ever released.  This preclinical CT offers 3-dimensional, high resolution (~50-100 micron) images and is well suited for imaging dense tissue, bone metastases, angiogenesis and phenotyping transgenic animals.
X-Ray µCT

MIR Preclinical Services owns and operates, on site, a GE RS150 micro-CT scanner. At present, this is a one of a kind instrument with unique hardware that was built to facilitate rapid, high resolution in vivo imaging. This equipment is capable of imaging both dense and soft tissue. MIR utilizes state-of-the-art equipment and is continually seeking new technologies to offer better services to it’s clients.

ANIMAL FACILITIES

MIR Preclinical Services utilizes Thoren MaxiMiser® and Biobubble® caging systems for animal housing. The Thoren MaxiMiser® caging systems supply and exhaust air through H.E.P.A. filters for each individual cage. Use of these caging systems minimizes pathogen exposure of the experimental animals on study by providing each individual cage with many complete air changes per hour. All animals housed in Thoren systems, regardless of immune status, are handled and treated in laminar down flow cabinets to minimize risks of environmental exposure. MIR has recently purchased a number of Biobubble® systems, slowly replacing the Thoren MaxiMiser® system in favor of this technology. Biobbubles are isolated enclosed units that shower contents within the bubble with hepafiltered air at 100 air changes per hour.  This system allows isolator cages to sit on racks within the bubble and work to be performed on stainless steel tables, all under the shower of hepafiltered air.  This sterile environment increases efficiency and separates animal colonies, minimizing possible environmental contamination within the facility.

This Biobubble system showers the inside of the unit with hepafiltered air at 100 air changes per hour.  Unlike the Thoren MaxiMiser® caging system, this system allows isolator cages to sit on racks within the bubble and work to be performed on stainless steel tables within the Biobubble, all under the shower of hepafiltered air.  This sterile environment increases efficiency and separates animal colonies, minimizing any possible spread of contamination within the facility.
Any subjects housed in Thoren MaxiMiser® cages are manipulated in laminar down-flow cabinets, regardless of immune status.  This minimizes the risks of contamination.
MIR's Thoren MaxiMiser® caging system houses subjects in cages that are individually ventilated with hepafiltered air at 100 air changes per hour.  Air is hepafiltered both in and out of the subject cages.

LABORATORIES

MIR Preclinical Services occupies approximately 20,000 square feet at its Ann Arbor facility that was specifically designed for efficient and flexible function. In addition to the imaging equipment and facilities noted elsewhere, the facility also has newly renovated and specifically designed biology, chemistry, tissue culture, and procedure labs.

MIR has a fully equipped biology and chemistry laboratory to support its preclinical in vitro and in vivo services offerings.
MIR has a fully equipped drug and sample preparation suite that is contiguous with the company's vivarium.

This is the view from inside one of MIR's Biobubbles within the vivarium.  Hepafiltered air is showered down from the ceiling, changing the total air in the bubble at 100 changes per hour.  This provides a total sterile environment for the animals as well as for proceedures.
