Abstract
Chimeric somatostatin-based polypeptides, polynucleotides used to encode the polypeptides, the methods for isolating and producing the polypeptides and the uses thereof are provided. In addition, low cost adjuvants for enhanced immunogenic response are provided. Vaccinations that include both chimeric somatostatin-based polypeptides and novel adjuvants are included, useful in facilitating farm animal productivity.
Claims5
A chimeric polypeptide having the immunogenicity of somatostatin, comprising:
- an amino acid sequence of somatostatin-14 represented by SEQ ID NO:
- 1 linked to a substantially inactive and truncated chloramphenicol acetyl transferase polypeptide having a sequence selected from the group consisting of SEQ ID NO:
- 4, SEQ ID NO:
- 8 and SEQ ID NO:
- 9,
- wherein the somatostatin-14 is linked to the inactive chloramphenicol acetyl transferase by a spacer sequence selected from SEQ ID NO:
- 11 or SEQ ID NO:
- 12.
