Once your strain is accepted, we will inform you which MMRRC facility will manage it. You will work closely with that facility throughout the remainder of the submission process. Additional information and documents will be required to transfer your strain. The strain will be cryopreserved, and a live breeding colony may be established if there is sufficient demand.

Unless accepted under Delayed Release, your strain will appear in the MMRRC Catalog under Accepted or In Development, and any registered interest will be tracked during preservation and colony establishment. Please direct interested investigators to the MMRRC website during and after this period.

Main Steps:

• Submit a Detailed Genotyping Protocol

  Download and complete the MMRRC Genotyping Protocol Template. For phenotypes identifiable by observation, include phenotyping methods and images to enhance the Strain Detail Sheet. Upload your completed file through your strain submission page or email it to sacoord@mmrrc.org with your submission ID in the subject line.

• Submit a Signed Donor Material Transfer Agreement (MTA)

  The MMRRC MTA (sample) is a formal agreement between you, your institution, and the MMRRC, authorizing distribution of your strain. It must be signed by both an authorized official (e.g., Technology Transfer) and the Submitting Investigator. Note: The MMRRC cannot negotiate or accept modifications to its MTAs. See MMRRC MTAs for details.

• Submit a Colony Health Status Report

  Provide a recent, institutionally certified health status report for your colony prior to shipment. The current health status will not affect acceptance. The assigned facility will assist you in obtaining this document.

• Ship Your Strain

  Once all documents are complete, coordinate with the assigned facility to arrange shipment. Additional shipment details may be required. See Transfer Methods.
