The Specimen Resource Locator (SRL) is a biospecimen resource database designed to help researchers locate resources that may have the samples needed for their investigational use.

Repository managers of domestic and publicly funded repositories that wish to make biospecimens more widely available to the cancer research community may submit an inquiry to add your repository to the SRL collections.

In the event you are unsuccessful in finding the appropriate specimen resource you may contact the NCI Tissue Expediter, a scientist, who can further assist you. Also, the Tissue Expediter can assist researchers to identify potential collaborators when needed. The NCI and the NCI's SRL do not oversee or take responsibility for the content, quality or data of the specimen collections or resources participating in the SRL.
