The synthetic polypeptide sequences, peptide conju gates and antibodies thereof are useful
as antigens in the production of vaccines, antiviral agents, diagnostic rea gents and the like,
for the detection and treatment of infectious and immune diseases such as polio and can
cer, and the like in mammals, particularly human be

The present invention relates to novel synthetic anti gens, conjugates and antibodies based
upon specific peptide sequences and the production thereof. More particularly, the invention
relates to a polypeptide which is a determinant site of a protein, the polypeptide having from
8 to 20 amino acid residues, having an amino-terminal amino acid and a carboxyl-terminal
amino acid, wherein the polypeptide includes:(a) a four amino acid sequence which
corresponds to the four amino acid sequence of a g-turn of the pro tein;(b) a sequence of two …
