Recombinant Anti-CTLA4 x Anti-PD1 Bispecific Antibody (VHH-Fc-VHH) (CAT#: HCAB-042)
Recombinant Anti-CTLA4 x Anti-PD1 Bispecific Antibody (VHH-Fc-VHH, Tetravalent HCAb) is a fusion protein of two diabodies connected together by an Fc region. In a diabody, the two VHHs with short linkers are from anti-CTLA4 and anti-PD1 antibodies. The VH and VL domains form an inter-chain pairing. The diabody with different specificities is fused to the Fc fragment, which results in 2+2 antigen-binding valency and exerts Fc-mediated functions or just extends the half-life. This BsAb can bind two factors simultaneously and enhance immune response. It is designed for the research of Tumors therapy.
