Abstract

Object matter of the invention is an optimized DNA sequence encoding the scFv(FRP5) antibody fragment. This novel sequence prevents the generation of the undesired by-product in the context of an scFv(FRP5)-ETA fusion protein, and possibly also other bacterially expressed scFv(FRP5)-containing fusion proteins. The DNA sequence of the scFv(FRP5) domain of scFv(FRP5)-ETA was modified by exchanging a distinct codon, thereby preventing an otherwise possible internal start of protein translation.
