With our general interest in antibody engineering and particularly Fc silencing we set out to analyse the Fc mutations that have been utilised in the clinic. Our efforts to obtain this information from other publicly available resources turned out to be fruitless and so instead we systematically cataloged, verified, analysed and annotated all antibody and Fc fusion proteins that have a registered international non-proprietary name (INN) with the World Health Organisation (WHO). We have amassed sequence information for over 800 antibody-based biologics and provide information on the primary amino acid sequence, design format, isotype, subtype, allotype and mutations. The searchable table below provides an overview of this information. Much more detailed information can be obtained from our publication and accompanying downloadable spreadsheet which can be accessed from the mAbs journal by clicking the image to the right.
