Recombinant Anti-CD2 x Anti-TCR (Vβ8) Bispecific Antibody (IgG(L)-scFv) is formed by an IgG and two scFv moieties. The scFv fragments from an anti-CD2 antibody are fused to the C terminus of an anti-TCR (Vβ8) IgG light (L) chains, or vice versa. It is a type of appended IgGs, which is bispecific and tetravalent (2+2 antigen-binding valency). This BsAb can activate T cells. It is designed for the research of Tumors therapy.
