Claim Text:
1. A glycosylated polypeptide selected from the group consisting of: (A) a SRIF14 consisting of the amino acid sequence of SEQ ID NO:1; (B) a polypeptide having 1 to 3 amino acids deleted from, substituted with, or added to SRIF14, SRIF14 consisting of the amino acid sequence of SEQ ID NO:1; and (C) a polypeptide having 80% or more homology with SRIF14 consisting of the amino acid sequence of SEQ ID NO:1, wherein said glycosylated polypeptide comprises (i) N amino acids at the N-terminal side, wherein N is an integer from 1 or more to 20 or less and/or (ii) M amino acids at the C-terminal side, wherein M is an integer from 1 or more to 6 or less, wherein said glycosylated polypeptide further comprises at least one amino acid substituted with a glycosylated amino acid, said at least one amino acid substituted with a glycosylated amino acid is present in any of said N amino acids, and/or said at least one amino acid substituted with a glycosylated amino acid is present in any of said M amino acids, and the polypeptide has affinity towards somatostatin receptors, and each of said glycosylated amino acids comprises a sugar chain represented by the following formula: wherein R 1 and R 2 are identical or different and are: and Ac is an acetyl group.
