Patent ID: 7297847

Claim:
An oligonucleotide consisting of: (a) one concatenation coding for a polypeptide with formula (P—K) n , where: n is selected from the group consisting of 3 (SEQ ID NO:12), 4 (SEQ ID NO:13), 5 (SEQ ID NO:14), 6 (SEQ ID NO:15), 7 (SEQ ID NO:16), 8 (SEQ ID NO:17), 9 (SEQ ID NO:18), 10 (SEQ ID NO:19), and 15 (SEQ ID NO:20); P represents a proline amino acid residue; K represents a lysine amino acid residue; the symbol “—” represents a bond between the two amino acid residues, the n (P—K) units also being bonded together by such bonds; and (b) optionally at least one lysine residue at the 5′ end or the 3′ end of said concatenation, or both.
