Recombinant Anti-EGFR x Anti-HER3 Bispecific Antibody (scFv-Fc-scFv)  (BSTF-156)

Recombinant Anti-EGFR x Anti-HER3 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-EGFR scFv is fused to the N-terminus of Fc via a hinge region while another anti-HER3 scFv is linked to the C-terminus of Fc. This scFv-Fc-scFv format has 2+2 antigen-binding valency by employing different scFv fragments. This BsAb can bind and inactivate two receptors simultaneously. It is designed for the research of Solid tumors therapy.
