Recombinant Anti-CD89 x Anti-S. pneumoniae Bispecific Antibody (Diabody-Fc)  (BSDBF-135)

Recombinant Anti-CD89 x Anti-S. pneumoniae Bispecific Antibody (Diabody-Fc) is a fusion protein of two diabodies connected together by an Fc region. In a diabody, the two scFvs with short linkers are from anti-CD89 and anti-S. pneumoniae 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 retarget NK cells to genus plasmodium. It is designed for the research of S. pneumoniae infection therapy.
