RRID — Research Resource Identifiers
Overview
RRIDs (Research Resource Identifiers) are persistent, unique identifiers for the reagents, tools, model organisms, software, and core facilities used in biomedical research. Developed by NIF (Neuroscience Information Framework) at UCSD and now coordinated through the SciCrunch Registry, RRIDs provide unambiguous citation of research resources in Methods sections, addressing the reproducibility problem caused by ambiguous reagent descriptions in publications. RRIDs are required or recommended by many journals including Nature, Science, Cell, and eLife.
RRID Categories
Each resource type is managed by a dedicated authority database:
| Category | Prefix | Authority |
|---|---|---|
| Antibodies | RRID:AB_ | Antibody Registry |
| Cell lines | RRID:CVCL_ | Cellosaurus (SIB/ExPASy) |
| Model organisms | RRID:IMSR_, RRID:MGI_, etc. | JAX, MGI, ZFIN, FlyBase, etc. |
| Software / tools / databases | RRID:SCR_ | SciCrunch Registry |
| Core facilities | RRID:SCR_ | SciCrunch Registry / CoreMarketplace |
