Patent ID: 7795382

Claim:
An inclusion body tag comprising the structure: [Ser-(Xaa 1 )-(Xaa 2 )-[Asp] a -(Xaa 3 )-(Xaa 4 )-(Xaa 5 )-[Asp-Pro] b -Leu-Gln-Gln-(Xaa 6 ) -Gln-[Asp-Pro] c ] n -[R] d (SEQ ID NO: 333) wherein a=0 or 1, b=0 or 1, c=0 or 1, d=0 or 1, and n=1-20 and wherein (Xaa1)=Arg or Glu; (Xaa2)=Arg or Glu; (Xaa3)=Pro or Gln; (Xaa4)=Arg, Glu, or Asp; (Xaa5)=Gln or Pro; (Xaa6)=Arg or Glu; and wherein when d=1 then n=1 or 2 and R is selected from the group consisting of a) His-His-Gln-Gln-Gln-Gln-Glu (SEQ ID NO: 334); b) Ser-Leu-Gly-Tyr-Gly-Gly-Leu-Tyr-Gly-Tyr (SEQ ID NO: 335); c) Glu-Glu; d) Glu-Glu-Glu; e) Glu-Glu-Glu-Glu (SEQ ID NO: 336); and f) Glu-Glu-Glu-Glu-Glu (SEQ ID NO: 337); wherein the inclusion body tag does not have the amino acid sequence as set forth in SEQ ID NO:139.
