Recombinant Anti-CD28 x Anti-CD3 Bispecific Antibody (scFv4-Ig)  (FVTIG-H230)

Recombinant Anti-CD28 x Anti-CD3 Bispecific Antibody (scFv4-Ig) is an appended IgG format, which includes four scFv moieties at the N-termini of the constant regions. It is a bivalent homodimer, in which one anti-CD28 scFv is fused to the CH1 domain of a heavy chain and another anti-CD3 scFv to the CL domain of a light chain, or vice versa. The resulting leads to 2+2 antigen-binding valency. This BsAb can improve T-cell activation. It is designed for the research of Tumors therapy.
