Recombinant Anti-Ad fiber knob x Anti-CEA Bispecific Antibody (scFv-Fc-scFv) is designed to be expressed as one chain, then assembled to a homodimer of bivalent scFv fragments and the Fc region of IgG. The anti-Ad fiber knob scFv is fused to the N-terminus of Fc via a hinge region while another anti-CEA scFv is linked to the C-terminus of Fc. Learn more: Ad fiber knob CEA scFv Fc scFv
