Recombinant Anti-CD20 x Anti-CD22 Tandem scFv-BGN immunotoxin (Bispecific Immunotoxin)  (BSFV-BGN004)

Recombinant Anti-CD20 x Anti-CD22 Tandem scFv-BGN immunotoxin (Bispecific Immunotoxin) is designed to be expressed as the Bouganin (BGN) fused to a tandem scFv recognizing CD20 and CD22. It contains a His-tag at the C/N terminus for affinity purification. This bispecific immunotoxin can deliver BGN to antigen-specific cells. Then BGN is a single chain, type I ribosone inactivating protein (RIP) and can kill the target cells. The bispecific immunotoxin is designed for the research of Lymphoma; Leukemia; Antoimmune disease; Immune dysfunction disease therapy.
