    摘要: Ligand-binding, dimerized polypeptide fusions comprising two polypeptide chains are disclosed. Each of the polypeptide chains comprises a ligand-binding domain of either a growth factor receptor or a hormone receptor joined to an immunoglobulin constant region polypeptide. Dimerization of the polypeptide fusion results in enhancement of biological activity. The immunoglobulin constant region polypeptide may comprise an immunoglobulin heavy chain constant region domain and hinge region.

    摘要: Methods for producing secreted receptor analogs and biologically active peptide dimers are disclosed. The methods for producing secreted receptor analogs and biologically active peptide dimers utilize a DNA sequence encoding a receptor analog or a peptide requiring dimerization for biological activity joined to a dimerizing protein. The receptor analog includes a ligand-binding domain. Polypeptides comprising essentially the extracellular domain of a human PDGF receptor fused to dimerizing proteins, the portion being capable of binding human PDGF or an isoform thereof, are also disclosed. The polypeptides may be used within methods for determining the presence of and for purifying human PDGF or isoforms thereof.

    摘要: Purified cytotoxic proteins for use within therapeutic compositions are disclosed. The proteins inhibit protein synthesis in vitro, exhibit abortifacient activity in mice, and contain proline residues with equivalent positions at residue 43 and residue 46 in ricin A-chain. A method for preparing such a cytotoxic protein from the tissue of Trichosanthes kirilowii is also disclosed. The proteins may also be used within a method for inhibiting protein synthesis in selected cells.
