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.

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.

Extra Providers

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