The BioSample Database stores information about biological samples used in molecular experiments, such as sequencing, gene expression or proteomics. It includes reference samples, such as cell lines, which are repeatedly used in experiments. Accession numbers for the reference samples will be exchanged with a similar database at NCBI, and DDBJ (Japan). Record access may be affected due to different release cycles and inter-institutional synchronisation.

Pattern for Local Unique Identifiers

Local identifiers in BioSample should match this regular expression:
^SAM[NED](\w)?\d+$

Example Local Unique Identifier

SAMEA2397676   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from BioSample should match this regular expression:
^biosample:SAM[NED](\w)?\d+$

Example CURIE

biosample:SAMEA2397676

Synapse.org external links

The metaregistry provides mappings between the Bioregistry and other registries. There are 8 mappings to external registries for this resource with 5 unique external prefixes.

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier SAMEA2397676 is used to demonstrate the providers available for BioSample. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.

Additional providers curated in the Bioregistry are listed here. These are typically inherited from Identifiers.org or Prefix Commons, and need extra curation.
