Below are links to additional resources that may provide necessary information for investigators seeking biospecimens for use in research.

NCI Specimen Resource Locator
This is a database to help researchers locate human specimens (e.g., tissue, serum, DNA/RNA, other specimens) for cancer research.

The CHTN has been providing biospecimens to the research community for more than 20 years and will continue to provide quality biospecimens to IRB-approved researchers for many more. 
This is a registry of federally and privately supported clinical trials conducted in the United States and around the world.

International Society for Biological and Environmental Repositories (ISBER)
ISBER provides information and guidance on the safe and effective management of specimen collections.

National Disease Research Interchange
The NDRI provides a number of human tissues, services, and initiatives to procure and supply normal and diseased tissues in support of medical and scientific research.

NCI Biospecimen Research Database
The Biospecimen Research Database is a free and publicly accessible database that contains peer-reviewed primary and review articles as well as standard operating procedures (SOPs) in the field of human biospecimen science.

NCI Cancer Diagnosis Program
The Cancer Diagnosis Program (CDP) strives to improve the diagnosis and assessment of cancer by effectively moving new scientific knowledge into clinical practice. This national program stimulates, coordinates, and funds resources and research on diagnostics and improved technologies to better characterize cancers, guide the treatment choice, as well as evaluate the treatment response.

NCI Physician Data Query (PDQ)
PDQ is NCI's comprehensive cancer database. PDQ contains summaries on a wide range of cancer topics, a registry of more than 8,000 open and more than 19,000 closed cancer clinical trials worldwide, and a directory of professionals who provide genetics services. PDQ also contains the NCI Dictionary of Cancer Terms, with definitions for more than 6,000 cancer and medical terms, and the NCI Drug Dictionary, which has information on more than 1,200 agents used in the treatment of cancer or cancer-related conditions.

NHLBI BioLINCC Biospecimen and Data Repository
The mission of BioLINCC is to facilitate access to, and maximize the scientific value of, the Biorepository and Data Repository and promote the availability and use of other NHLBI funded population-based biospecimen and data resources.

NIDDK Central Repository
The NIDDK has established data, biospecimens, and genetic repositories to increase the impact of current and previously funded NIDDK studies by making their data and biospecimens available to the broader scientific community.

NIH NeuroBioBank
The NIH NeuroBioBank brings together multiple stakeholders including brain and tissue repositories to facilitate research advancement through the collection and distribution of human post-mortem brain tissue.
