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

Providers

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. A guide for curating additional providers can be found here.
