The aim is to capture every sequence in the public domain that contains a light or heavy antibody variable domain, using a simple similarity protocol.

To avoid experimentally unverified sequences, pseudogenes etc. the selection is restricted to certain data classes and taxonomic divisions and requires that there is a protein translation.

Every protein translation downloaded from the EMBL release directory is used as a query sequence in a conservative BLAST search of three reference sets of known Ig variable domain sequences.

The reference sets are:

The overwhelming majority of queries (95%) that get a match in one set get a hit in all of them.

Entries with a translation that gets a match are collected and the protein identifiers of the translations are recorded.
