== Publication Abstract from PubMed ==
Technologies for the production of bispecific antibodies need to overcome two major challenges. The first one is correct heavy chain assembly, which was solved by knobs-into-holes technology or charge interactions in the CH3 domains. The second challenge is correct light chain assembly. This can be solved by engineering the Fab-arm interfaces or applying the immunoglobulin domain crossover approach. There are three different crossovers possible, namely Fab-arm, constant domain and variable domain crossovers. The CrossMabCH1-CL exchange does not lead to the formation of unexpected side products, whereas the CrossMabFab and the CrossMabVH-VL formats result in the formation of typical side products. Thus, CrossMabCH1-CL was initially favored for therapeutic antibody development. Here, we report a novel improved CrossMab design principle making use of site-specific positional exchanges of charged amino acid pairs in the constant domain of these CrossMabs to enable the correct light chain assembly in the CrossMabVH-VL and improvements for the CrossMabFab design.
