(Figure Presented) Getting together and breaking up: Circular arrays of recombinant antibodies can be produced reversibly by chemically controlled protein macrocyclization. In the presence of bismethotrexate (bis-MTX), dimeric dihydrofolate reductase fusion protein (DHFR) with an anti-CD3 single-chain variable region (scFv) self-assembled spontaneously into diabodies, which were disassembled into monomers with an excess of the antibiotic trimethoprim (see picture).
