Recombinant Anti-HER2 x Anti-HER3 Bispecific Antibody (Diabody-Fc) is a fusion protein of two diabodies connected together by an Fc region. In a diabody, the two scFvs with short linkers are from anti-HER2 and anti-HER3 antibodies. The VH and VL domains form an inter-chain pairing. The diabody with different specificities is fused to the Fc fragment, which results in 2+2 antigen-binding valency and exerts Fc-mediated functions or just extends the half-life. This BsAb can bind and inactivate two receptors simultaneously. It is designed for the research of Breast cancer; Gastric cancer; Prostate cacncer; Ovarian cancer; Solid tumors therapy.
