Abstract
Chimeric polypeptides having the immunogenicity of somatostatin include an amino acid sequence of somatostatin-14 and a protein carrier. The sequence of somatostatin-14 is joined to the 3′-end of the protein carrier by a spacer (Sp)n, wherein Sp consists of an alkaline amino acid and an amino acid that provides a rigid expended chain-like β-structure, and n designates the number of blocks in the spacer. In a preferred embodiment, n is from 1 to 8 and the protein-carrier is chloramphenicol acetyl transferase (CAT).
