  • Patent number: 8318472
    Abstract: An optimized nucleic acid sequence encoding the immunoconjugate VB4-845 is disclosed. Modifications to the original VB4-845 nucleic acid sequence include optimization of the sequences encoding the VH region, VL region, linkers and pseudomonas exotoxin A. The modifications improved the yield of VB4-845 in an Escherichia coli expression system.
