Patent ID: 7355019

Claim:
A biological conjugate, comprising: (a) a targeting moiety comprising a polypeptide having an amino acid sequence comprising SEQ ID NO:2 and the polypeptide sequence of a selected targeting protein selected from the group consisting of human vascular endothelial growth factor (VEGF) comprising the sequence of SEQ ID NO: 6 or SEQ ID NO: 8, human annexin V comprising the sequence of SEQ ID NO: 10, a catalytically inactive fragment of anthrax lethal factor comprising the sequence of SEQ ID NO: 12, and a single chain vascular endothelial growth factor (scVEGF) comprising the protein sequence of SEQ ID NO: 4 or SEQ ID NO: 14; and (b) a binding moiety selected from the group consisting of drugs, radionuclide chelators, polyethylene glycol, dyes, lipids, liposomes, a surface of a nano- or microparticle, a surface of a dendrimer, a surface of a tissue scaffold, a surface of a biomedical device, and a surface of a biosensor; said biological conjugate having a covalent bond between the thiol group of SEQ ID NO:2 and said binding moiety.
