methods are described. Anti-TFR (Fv)-PE40 contains DNA for the antigen binding portion
(Fv) of a monoclonal antibody directed at the human trans ferrin receptor fused to the DNA
for a 40,000 molecular weight fragment of Pseudomonas exotoxin (PE40). In another fusion
protein, DT388-anti-TFR (Fv), DNA for the antigen binding portions of the anti-TFR antibody
has been fused to the DNA encoding a truncated form of Diphtheria toxin. In anti-TFR (Fv) …
