  • Patent number: 5496924
    Abstract: A fusion protein including a ballast portion and a desired protein. The ballast portion forms either the C- or N-terminus of the fusion protein, and the ballast portion includes a part of the amino acid sequence of interleukin-2 (IL-2). According to certain preferred embodiments, the ballast portion includes approximately the first 100 amino acids of IL-2. According to other preferred embodiments, the ballast portion contains fewer than 100 amino acids of IL-2. According to further advantageous embodiments, a synthetic IL-2 gene is divided by unique cleavage sites into 6 segments, any number of these segments can be linked in arbitrary sequence. These embodiments permit specific instructions with which the solubility of the fusion protein can be altered, and thus the fusion proteins can readily be separated from soluble proteins intrinsic to a host. The DNA coding for the fusion proteins, as well as vectors and hosts are also provided.

  • Patent number: 5494895
    Abstract: A thirty-nine amino acid peptide, Margatoxin (MgTX), is purified to homogeneity from venom of the scorpion Centruroides margaritatus. The gene encoding MgTX is constructed and this gene is expressed in E. coli, to produce recombinant MgTX. MgTX is a potent and selective inhibitor of a voltage-dependent K.sup.+ channel present in human lymphocytes. MgTX exhibits immunosuppressant activity with human T-lymphocytes, and is useful as an immunosuppressant, in modeling nonpeptidyl K.sup.+ channel blockers, and in establishing biochemical assays based on ligand binding or other protocols with which to screen for other novel modulators of voltage dependent K.sup.+ channels in lymphocytes and other tissues including the brain. As an immunosuppressant, MgTX is useful in the treatment of autoimmune diseases, the prevention of rejection of foreign organ transplants and/or related afflictions, diseases and illnesses.

  • Patent number: 5478804
    Abstract: Conjugates comprising bFGF or other FGF polypeptides and a cytotoxic agent are prepared. The cytotoxic agent can be a ribosome-inactivating protein (RIP), such as saporin, which is attached to bFGF through a chemical bond, or the composition can be prepared as a recombinant DNA chimera. The conjugates are used to specifically target cells, in vivo and in vitro, which express FGF receptors. The cytotoxicity of the conjugates is proportional to the number of receptors expressed by a cell type. The conjugate is useful to effectively treat mammals, and in particular human patients, afflicted with tumorigenic conditions, such as human melanomas, human ovarian carcinomas, teratocarcinomas and neuroblastomas, and other FGF-mediated tumors caused by a proliferation of cells which express FGF receptors.
