Synthetic schematic of MATCH nanoconjugates. (A) Synthetic scheme of generating Fab′-MORF conjugates from whole antibody starting material. (B) Linker coupling of 3′-amine functionalized morpholino oligonucleotides using a bifunctional ethylene glycol dimer. (C) Hybridization of two complementary Fab′-MORF conjugates. Conventionally, Fab′-MORF1 conjugates are B-cell engagers and Fab′-MORF2 conjugates are T-cell engagers. (D) Chemical structure of bifunctional oligoethylene glycol (PEG) linker. (E) Size exclusion chromatogram overlay of Fab′CD20-MORF1 (blue), Fab′CD19-MORF1 (red), and Fab′CD3-MORF2 (green) products used in this study. Chromatographs were detected on a Superdex 200 10/300 GL column in PBS (pH 7.4) at 0.4 mL min−1.
