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.
