Patent ID: 8303959

Claim:
A composition comprising one or more purified polypeptides, wherein the one or more polypeptides consist of an amino acid sequence set forth as SEQ ID NO:6, or consist of at least 17 contiguous amino acids of an amino acid sequence set forth as SEQ ID NOs:4, 5, 7, 9, 11, 15, 16, 17, 18, or 20 or consist of a polypeptide having at least about 94% identity to any one of SEQ ID NOs: 15, 16, 17, 18, or 20, or consist of a polypeptide having less than 40 amino acids and having at least about 94% identity to SEQ ID NOs: 4, 5, 6, 7, 9, or 11; wherein, optionally, the one or more purified polypeptides are linked to an indicator reagent, a signal sequence, a stop transfer sequence, an amino acid spacer, a transmembrane domain, a protein purification ligand, a heterologous polypeptide, a moiety that enhances an immune response, a moiety that facilitates purification, a moiety that facilitates polypeptide stability, one or more additional polypeptides comprising any one of SEQ ID NOs:1-21 or a combination thereof.
