KabatMan - Kabat Sequence Database Statistics

Statistics for the number of sequences contained in the Kabat antibody sequence database.

Only immunoglobulin sequences are stored here; all T-cell receptor, MHC sequences, etc. are rejected. In addition, sequences with fewer than 75 residues are rejected so that the database contains only essentially complete light or heavy chain sequences.

Complete antibodies are those which have both light and heavy chains. These are defined by ensuring the species, sequence name and author details match between the chains. The raw data contains no other pointers to link light and heavy chains to one another.
