Recombinant Anti-FAS x Anti-CSPG4 Bispecific Antibody (Tandem scFv) is designed to be expressed as a scFv from an anti-FAS antibody variable domains fused with a scFv from an anti-CSPG4 antibody variable domains. It contains a His-tag at the C/N terminus for affinity purification. The BsAb exits as monomer in reducing and non-reducing conditions. This BsAb can induce targeted apoptosis. It is designed for the research of Melanoma therapy.
