    摘要: Targeting molecules are provided for use in delivering imaging agents to epithelial tissue. The targeting molecule comprises a polypeptide that forms a closed covalent loop, contains at least three peptide domains having β-sheet character, each of the domains being separated by domains lacking β-sheet character. The targeting molecule specifically binds to a basolateral factor attached to a basolateral domain of an epithelial cell surface causing internalization of a linked imaging agent into the cells. The polypeptide or imaging agent may be linked to a peptide amino acid sequence that directs delivery of the imaging agent to a carcinoma cell, a nucleus, or an endoplasmic reticulum.

    摘要: Targeting molecules for use in delivering imaging agents to epithelial tissue are disclosed. Upon delivery, the imaging agent(s) may remain within an epithelial cell or may undergo transepithelial transport via transcytosis. The targeting molecules may be used, for example, for diagnostic techniques. The targeting molecule is a polypeptide, which may be produced by recombinant methods, that forms a closed covalent loop, contains at least three peptide domains having .beta.-sheet character which are separated by domains lacking .beta.-sheet character, specifically binds to a basolateral factor attached to a basolateral domain of an epithelial surface causing uptake of a linked imaging agent into cells of the epithelial surface, and is not a full length dimeric Iga. Preferably, the polypeptide is a J chain polypeptide, or a J chain polypeptide linked to an immunoglobulin heavy chain without an immunoglobulin light chain.
