AbDb: Antibody Structure Database

Search Antibody Structures

This page provides access to processed antibody structural data. Antibody-antigen complexes obtained from the PDB can be downloaded, as well as non-complexed antibody. Structural data for Bence-Jones and Camelids antibodies has also been provided. All datasets are available in three different numbering schemes; Kabat, Chothia and Martin.
