WebDec 5, 2013 · Abstract. Heterodimeric Fc designed by engineering the CH3 homodimeric interface of immunoglobulin G1 serves as an attractive scaffold for the generation of bispecific antibodies (bsAb) due to the favorable properties of the Fc region. In this study, we describe a heterodimeric Fc generated by substituting the conserved electrostatic … In previous work, we generated a monomeric Fc variant, C4 (now renamed MFc1), from a rationally designed IgG4 phage library containing a set of mutations in the CH3 domain to fully stabilize the disruption of the Fc dimer interface (Fig. 1a). To extend the compatibility of these dimer-disrupting mutations … See more Based on SEC-MALS and DSF results, the S354E mutation was selected to be explored for the general applicability of the MFc platform.
