Abstract

By combining and cross-checking data from the World Health Organization's lists of international nonproprietary names with three other databases, we assembled a dataset of amino acid sequences of 819 antibody-related therapeutics. This enabled the systematic tabulation of 57 different molecular formats and about 90 different constant-region variants (47 for silencing, 14 for enhancement, 8 for modifying binding to FcRn, 13 for heterodimerization, 4 for site-specific modification and 4 for stabilization), as well as the frequencies of different targets and immunoglobulin allotypes. The curated dataset provides a resource for researchers, giving insights into trends in antibody engineering and a guide to the most frequently tested designs.

Keywords: Allotype; FC receptor; FC region; immunoglobulin fusion protein; immunoglobulin sequence; international nonproprietary name; therapeutic antibody.
