CBA Metabolic Phenotyping (MEP)

Overview of Services

The Metabolic Phenotyping (MEP) Core is a Scientific Service within the Center for Biometric Analysis. MEP provides state-of-the-art metabolic phenotyping support and scientific consulting, including assistance with experimental design, data analysis and interpretation, as well as training for researchers interested in becoming proficient in the skills necessary to conduct metabolic phenotyping. The staff uses standardized techniques in the study of metabolism, diabetes, and obesity.

MEP employs Sable System’s Promethion Metabolic Home Cage Systems for continuous measurement of energy expenditure by indirect calorimetry, food intake, and locomotor activity (wheel running optional). Additional measurements include body composition for both fat and lean mass using NMR and DEXA, and glucose homeostasis through glucose and insulin tolerance testing.


To discuss a new project, please go to the iLAB site for the Center for Biometric Analysis and initiate a Consultation Request.
