Fig. 1. Generation of combinatorial binder/format bsAb matrices via dummy-Fc driven assembly.
a Affinity tag-containing dummy chains drive bsAb assembly and enable one-step purification. b Combination of educts of different formats generates bsAb format diversity. Green circles indicate the location of paratopes in output formats. c Combining binders in different input formats multiplies the binder–format design space. Each product within the matrix is a unique bsAb with a specific binder combination in a specific format.
