The National Institutes of Health (NIH), through the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), has announced a funding opportunity titled "NIDDK Central Repository Non-renewable Sample Access." This initiative allows researchers to apply for access to valuable non-renewable biological samples and associated data from significant clinical studies housed at the NIDDK Central Repository, aimed at advancing research in diabetes, obesity, kidney, and digestive diseases. The program does not provide funding; instead, it facilitates access based on the merit of applications and sample availability, with a submission period running from September 27, 2022, to June 27, 2025. Interested applicants must provide a report from the NIDDK Central Repositories documenting sample availability and can reach out to the NIH OER Webmaster at OERWebmaster03@od.nih.gov for further inquiries.
