Recombinant Human Anti-FN1 x Human Anti-HSG Bispecific Antibody (scFv-Fc-scFv)  (BSTF-H329)

Recombinant Anti-FN1 x Anti-HSG 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-FN1 scFv is fused to the N-terminus of Fc via a hinge region while another anti-HSG 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 be used in pretargeting system of PET, radioimaging or radiotherapy. It can mediate targeting of radioactivity to tumor cells. It is designed for the research of Solid tumors imaging and therapy.
