The Sample database provides experimental biological source materials retrieval. Original datasource of sample database includes CNSA, EBB, NCBI BioSample etc. The main available information includes sample name, organism, sample type, description, etc.

Data resources date:

Sample database comprises sample data from CNSA and external web source NCBI BioSample. CNGBdb acquires sample data from NCBI BioSample via FTP. All data obtained from FTP are parsed and integrated according to certain meta-information structure, and displayed on the page in order to provide search, retrieval and download services for users. Every sample data (e.g. https://db.cngb.org/search/sample/SAMN00183644/) includes the original source ID which can be clicked to the NCBI BioSample details page.

CNGBdb complies with the data usage agreement and related requirements of these source databases. If you have any question about the above methods of data references or think that the data references are not reasonable, please contact CNGBdb@cngb.org.
