Recombinant Anti-DR5 x Anti-FAP Bispecific Antibody (scDiabody-Fc) is a fusion protein of two scDiabodies with an Fc region. In single-chain Diabodies, an additional connecting linker is introduced between chains of the anti-DR5/anti-FAP diabody. The scDiabody with two specificities is further fused to the Fc domain to form BsAb with 2+2 antigen-binding valency. This BsAb can induce targeted apoptosis by activation of the death receptor. It is designed for the research of Breast cancer; Ovary cancer; Colon cancer; Lung cancer therapy.
