Recombinant Anti-gp40 x Anti-TFRC Tandem Fab-NGB immunotoxin (Bispecific Immunotoxin)  (BSFAB-NGB012)

Recombinant Anti-gp40 x Anti-TFRC Tandem Fab-NGB immunotoxin (Bispecific Immunotoxin) is designed to be expressed as the Nigrin b (NGB) fused to a tandem Fab recognizing gp40 and TFRC. It contains three chains and a His-tag at the C/N terminus for affinity purification. The two Fd regions are connected by a flexible linker. This bispecific immunotoxin can deliver NGB to antigen-specific cells. Then NGB is a lectin and can kill the target cells. The bispecific immunotoxin is designed for the research of Colon cancer; Ovarian cancer therapy.
