KIH IgG-scFab, a new form of appending IgG-like bispecific antibodies, is engineered by fusing a scFab domain to the C-termini of IgG heavy chain modified by knobs-into-holes (KIH) technique. Hence, when co-expressed in one cell, Knob-modified Fv tend to pair with Hole-modified Fv, which effectively results in the production of asymmetric antibodies with dual specificities. Up to now, variant approaches have been established based on KIH method, such as using alternative mutations, electrostatic steering effects, or hybrid CH3 domains derived from IgG and IgA. KIH IgG-scFab can effectively prevent the formation of homodimer which inevitably happens during conventional bispecific IgG synthesis. Furthermore, this strategy makes it feasible to produce BsAb in industrial scale.
