FabRICATOR and GingisKHAN

The Monoclonal Antibody Project initiated by The Consortium for Top Down Proteomics (CTDP) aims to assess top-down mass spectrometry approaches for antibody characterization. It is a multicentre study, where the participants use several workflows (for example top-down sequencing, middle-down sequencing and intact mass analysis) to investigate the detailed structure and modifications of three monoclonal antibodies. Both intact antibodies and antibody subunits are thoroughly investigated in the study, and Genovis FabRICATOR and GingisKHAN enzymes are used to produce the subunits. FabRICATOR digests antibodies into F(ab’)2 and Fc fragments, and GingisKHAN into intact Fab and Fc fragments, and detailed protocols on how to use these enzymes are available from our website (Genovis IgG Proteases) and also from CTDP’s newly launched website (Top Down Proteomics Methods). The project is coordinated by Yury Tsybin from Spectroswiss Sarl, Joe Loo from UCLA and Kristina Srzentic from Northwestern University, and preliminary results are planned to be presented this fall!
