Access, Submission, and Pricing


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


Sample Preparation

For sample preparation protocols, please see the Reference Section.
