Established in 2016, CREx is an NIH-exclusive online research resource marketplace designed to increase transparency around the advanced technologies and technical expertise available within the Intramural Research Program (IRP). It also serves to foster collaboration and resource sharing across NIH Institutes and Centers.
CREx catalogs more than 250 internal NIH research resources—including Core Labs, Collaborative and Trans-NIH Facilities, and NIH-funded data and resource repositories. Resources are organized by research areas and keywords to help NIH investigators easily identify the most relevant tools and expertise needed to accelerate scientific discovery.
Transition Notice:
Effective October 31, 2025, CREx discontinued the following services:
- Access to a searchable marketplace for external research services
- Direct communication and comparison tools for all service providers
CREx continues to provide a centralized, searchable database of NIH IRP Core Labs, Collaborative and Trans-NIH Facilities, and NIH-funded data and resource repositories.
Operational guidelines, project prioritization, and capacity for accepting external projects are determined by each host Institute/Center. For questions regarding access, please refer to the user guidelines for the specific core or contact the designated point of contact (POC).
The CREx newsletter is now published and accessible on the NIH CREx SharePoint Site.
