Facility Details

Do you have an animal model that is large/small with a given intervention (diet, gene, drug)?

Do changes in energy intake quantitatively explain body mass phenotype?

Does efficiency of the digestive tract to extract calories contribute to body mass phenotype?

What is the hydration status and fluid reservoir distribution of my animal model?

We at the Medical College of Wisconsin Comprehensive Rodent Metabolic Phenotyping Core (CRMPC) can help answers these questions!

The CRMPC provides guided access to novel technologies for complete dissection of energy flux in rodents and other small animals. Our expert staff assist in development, testing, and standardization of metabolic technologies and workflows to leverage both mouse and rat models of interest to the MCW research community. The centerpiece of the CRMPC is our 16-cage multiplexed metabolic phenotyping system (Promethion, Sable Systems International) that provides detailed mechanistic dissection of resting metabolic rate (RMR), physical activity, and ingestive behaviors of rodents in home style cage designs across the light cycle. In addition, the CRMPC combines RMR assessments with direct/combined calorimetry (total heat dissipation) to enable assessment of anaerobic forms of energy expenditure (gut microbiome). Additional services include body composition analysis (via NMR), bone content and density analysis (via DEXA), metabolic caging, indirect calorimetry, bioimpedance spectroscopy, thermal imaging. Our core experts provide guidance for experimental design, execution of studies, statistical analysis of resulting data, and regulatory assistance and compliance. Contact core manager John J. Reho (jreho@mcw.edu) to discuss your research needs!
