Here we show that replacing the Lys with an arginine (Arg) residue affords an orthogonal ADC assembly that is site-selective and stable. X-ray crystallography confirmed the location of the reactive Arg residue at the bottom of a deep pocket. As the Lys-to-Arg mutation is confined to a single residue in the heavy chain of the DVD-IgG1, heterodimeric assemblies that combine a buried Lys in one arm, a buried Arg in the other arm, and identical light chains, are readily assembled. Furthermore, the orthogonal conjugation chemistry enables the loading of heterodimeric DVD-IgG1s with two different cargos in a one-pot reaction and thus affords a convenient platform for dual-warhead ADCs and other multifaceted antibody conjugates.
