Patent ID: 7585943

Claim:
A chimeric protein comprising a protein of interest, a fusion partner, and a peptide linker interposed there between, wherein said protein of interest is linked to the N-terminus of said peptide linker and said fusion partner is linked to the C-terminus of said peptide linker or said protein of interest is linked to the C-terminus of said peptide linker and said fusion partner is linked to the N-terminus of said peptide linker, wherein the peptide linker consists of the sequence Pro-Arg-Gly-Ser-Pro-Arg-Ala-Ser (SEQ ID NO:7) or the sequence Leu-Val-Pro-Arg-Gly-Ser-Pro-Arg-Ala-Ser (SEQ ID NO:8), and wherein said fusion partner is an affinity peptide.
