Recombinant Anti-CD89 x Anti-S. pneumoniae Bispecific Antibody (scFv-IgG)  (BSSG-135)

Recombinant Anti-CD89 x Anti-S. pneumoniae Bispecific Antibody (scFv-IgG) is formed by an IgG and two scFv fragments. The scFvs from an anti-CD89 antibody variable domain are respectively connected to the N terminus of the anti-S. pneumoniae IgG heavy chains or light chains to form scFv-(H)IgG or scFv-(L)IgG. It is a type of appended IgGs and has 2+2 antigen-binding valency. This BsAb can retarget NK cells to genus plasmodium. It is designed for the research of S. pneumoniae infection therapy.
