Metabolomics Facility


CRI’s Metabolomics Facility provides services through a cost-sharing approach in which users are charged according to instrument time. Our staff consults with potential users to discuss experimental design and costs. Users then submit a sample form to estimate costs of the experiment. Staff is also available to discuss data interpretation after the experiment. To get started, please contact Lauren Zacharias.
