# BioSample accession (`biosample_accession`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Accession of a biological sample description in the BioSample databases of NCBI, EMBL-EBI and DDBJ. Sequencing, gene expression and proteomics submissions point to it to say which material was analysed. It is SAM, a letter for the issuing centre (N, E or D), an optional further letter and digits.
