Current Guidelines


Commercial antibody RRCs provided here include a vendor name, catalog number, Lot number and an RRID that is derived from the Antibody Registry (ABR) authority:

      DSHB Cat# RC2, lot# 123, RRID:AB_531887

While a vendor, catalog and lot number may be a sufficient for uniquely identifying most antibodies, an Antibody Registry identifier is useful in virtue of how antibodies are cataloged and distributed across vendors - which often results in a single antibody becoming associated with numerous catalog numbers. The Antibody Registry associates each unique antibody with a registry identifier that tracks with this reagent throughout its lifetime, no matter how its catalog number or vendor may change. We strive to provide this information, however antibody origins may be hidden by some vendors and this will cause the same antibody to have several RRIDs. 

Lab-Sourced antibodies are also a target for inclusion in the registry, but we depend largely on users like you to register them. An submission portal currently resides here for any antibody (commercial or lab-sourced) not found in the registry database, which will return an identifier for immediate use and authors should expect an official answer from the antibodyregistry curators within 1 business day.

Cell Lines

Cell line identifiers provided here include a standard name, the provider, the catalog or clone number and RRID based on a Cellosaurus identifier:

      KCLB Cat# 10020.2, RRID:CVCL_2260

The Cellosaurus database is the most complete curated database of cell lines on the web and staff take care of cross-linking data between vendors and ontologies. Importantly the International Committee on Cell Line Authentication, ICLAC, which puts together a list of contaminated cell lines is also included in Cellosaurus as soon as it it made public. This ensures that authors searching for their RRIDs will easily find information about any adverse events reported with the cell line before they publish their papers. They can decide whether or not the conclusions of their study will be affected by the report.

To obtain an RRID for a cell line that is not currently found in the RRID portal please contact Cellosaurus, the authority on cell lines. Cellosaurus will take your information and generate an RRID for your cell line in 1-2 business days:

Do you wish to deposit a cell line?

The following bioresource centers distribute authenticated cell lines, following the ANSI standard for human cell line authentication. Some of these will also allow researchers to submit their cell lines. Please contact your local cell line stock center to deposit cell lines.

Software Tools and Databases

Software tool and database citations provided here include a standard tool name, the provider, a version number if available, and RRID based on a NIF SciCrunch Registry identifier:

       CellProfiler Image Analysis Software, V2.0, RRID:SCR_007358

At present the recognized authority for software tools is the NIF SciCrunch Registry, which focuses largely on non-commercial tools, but as our content expands new sources of tools will be included. When a single tool is referenced with different identifiers in different sources, they will be cross-referenced in our system. A recommended name and the providing organization is also included in the RRC. This offers important provenance information which can be relevant for obtaining the resource, and for documenting any code modifications at in a particular implementation. Any tools that are not found in the Resource Identification Portal should be registered with the NIF SciCrunch Registry as a "General Resource" here, and an identifier will be supplied for use in your publication.
