2017-06-22New: Scheduled maintenance (9:30-12:00, 28th, June)

From 9:30 to 12:00 (planned), 28th, June, the DRA, BioProject and BioSample submission and search services will be unavailable due to scheduled maintenance.

The BioSample database was developed to serve as a central location in which to capture and store descriptive information about the biological source materials, or samples, used to generate experimental data in any of DDBJ’s primary data archives. Typical examples of a BioSample include a cell line, a primary tissue biopsy, an individual organism, or an environmental isolate.

The data are shared among DDBJ, EBI and NCBI BioSample databases; all sample information in one of these databases will also be held in the other database.

The general aims of this project include:

  • Allowing submitters to explicitly indicate when the same samples have been used across multiple studies.
  • to provide a submission portal that promotes the use of controlled vocabularies for sample attributes, thus helping to harmonize sample descriptions across databases.
  • to link samples to corresponding experimental data in multiple archival databases, making it possible for users to aggregate all available data derived from a given sample.
