COVID-19-related Disruptions
 April 03, 2020
Due to the current situation with COVID-19, we are operating with reduced staffing and there may be delays in responding to emails and phone calls at this time.  In addition, because of institutional restrictions and uncertainty with courier services, the MMRRC is currently shipping or receiving live animals on a case-by-case basis.  Please contact us to discuss your needs.  For ongoing orders, we will continue to communicate frequently to keep you apprised of the status of your order.  Thank you for understanding.

Microbiota Characterization
 April 02, 2015
The gut microbiota (GM) is now recognized as a key factor in health and disease.  Differences in the composition of the gut microbiota of research animals may contribute to altered phenotypes or poor reproducibility of animal-based studies.  Culture-independent techniques such as next-generation sequencing (NGS) allow in-depth characterization of the gut microbiota.  The MMRRC now offers a full line of NGS-related services including fecal DNA extraction, 16S rDNA gene sequencing, and informatics analysis to researchers using mouse models.  For more information, please see here or contact
