IgG-v bispecific antibodies are engineered by appending paired antibody variable domains Fv to the N or C terminus of the heavy or the light chain of an antibody, resulting in multi specific molecules with two binding sites for each antigen. They are the major class of appending IgG-like molecules which provide great starting points to design the most appropriate therapeutic antibodies so as to achieve the expected mechanisms and application potential. Depending on the strategy used for appending Fv to the whole IgG, there are four different formats of IgG-v BsAbs:
