How To Contribute

The Central Biorepository is a repository of human biospecimens that serves as a central storage facility, point-of-research access, and administrative hub for research using these biospecimens and data associated with or derived from them.

The repository inventory is created through partnerships with investigators, departments, centers, and institutes who are looking to create a resource for their own use, as well as providing biomaterials and collaborative opportunities to the research enterprise at University of Michigan and beyond. In most cases, the CBR assists in the establishment of new, prospective research collections and protocols. Our governance policies allow for some retrospective collections to be stored at the Central Biorepository after approval by the CBR Governance Committee.

Prospective CBR collections use a standardized streamlined Biorepository Information Pamphlet  and a Biorepository Consent Template for prospective biospecimen donors to review and sign. This consent form permits broad use and sharing of biospecimens and data. CBR staff assist researchers in developing IRB applications for creating a CBR collection, and provide guidance throughout the process.

Benefits of contributing to the Central Biorepository include:

  • Opportunities for collaboration and innovation through sharing
  • Secure, controlled storage of precious resources
  • Study personnel are free to do research, not freezer management

If you would like to contribute to the Biorepository, please complete and submit the Request for Prospective Collection Services form. If you’d like the CBR to manage a retrospective collection of specimens, please complete and submit the Request for Retrospective Collection Services form.  

Additional Information:

  • The full life cycle of specimens submitted to the biorepository is tracked using a Laboratory Information Management System (LIMS). CBR staff will work with you to establish your study and specimen requirements in the LIMS.

The primary cold storage environment in use at the CBR is the vapor phase of liquid nitrogen (LN2). Other storage temperatures are available if required. Contact us via email at or by calling 734.647.8809 to discuss your requirements.
