Patent number: 6716606Abstract: Disclosed are novel polypeptides possessing part or all of the primary structural conformation and one or more of the biological properties of a mammalian (e.g., human) pluripotent granulocyte colony-stimulating factor (“hpG-CSF”) which are characterized in preferred forms by being the product of procaryotic or eucaryotic host expression of an exogenous DNA sequence. Sequences coding for part or all of the sequence of amino acid residues of hpG-CSF or for analogs thereof may be incorporated into autonomously replicating plasmid or viral vectors employed to transform or transfect suitable procaryotic or eucaryotic host cells such as bacteria, yeast or vertebrate cells in culture. Products of expression of the DNA sequences display, e.g., the physical and immunological properties and in vitro biological activities of isolates of hpG-CSF derived from natural sources. Disclosed also are chemically synthesized polypeptides sharing the biochemical and immunological properties of hpG-CSF.Type: GrantFiled: November 6, 2001Date of Patent: April 6, 2004Assignee: Amgen Inc.Inventor: Lawrence M.

Patent number: 5151511Abstract: Novel polypeptides possessing biochemical and immunological properties of avian growth hormone are obtained by practice of recombinant DNA procedures. Novel DNA sequences are disclosed which are capable of directing the synthesis of such polypeptides in selected host microorganisms. In a preferred embodiment, a novel polypeptide with the properties of avian growth hormone of chicken species origins is produced as a result of bacterial expression of a novel plasmid, cGH-T21. This plasmid is harbored in transformed E. coli C600 cells deposited as A.T.C.C. 39182. Also disclosed is a DNA sequence capable of directing the synthesis of a novel polypeptide with the properties of avian growth hormone of turkey species origin.Type: GrantFiled: January 27, 1988Date of Patent: September 29, 1992Assignee: Amgen Inc.Inventors: Lawrence M.

Patent number: 4918162Abstract: Methods and compositions are provided for identifying patients suffering from cancer, particularly neural and neuroendocrine cancers. It has been found that the protein expression product of the human N-mcy proto-oncogene may be detected in certain biological specimens, particularly tissue specimens and sputum samples. By obtaining immunogenic N-myc polypeptides, either synthetically or by isolation from a natural source, antibodies specific for the N-myc protein are obtained. Those antibodies may then be used in immunological techniques for detecting the presence of N-myc in the biological samples. In particular, the antibodies may be employed in immunohistochemical techniques to detect the N-myc protein in prepared tissue and sputum samples.Type: GrantFiled: October 5, 1988Date of Patent: April 17, 1990Assignee: The Regents of the University of CaliforniaInventors: Dennis J.

Patent number: 4666839Abstract: Disclosed are methods for selective modification of double-stranded DNA sequences facilitating their storage and incorporation into expression vectors. Manufactured partially double-stranded DNA primers are hybridized to complementary regions of single-stranded forms of DNA sequences to be altered. Desired, selectively modified double-stranded DNA sequences are then formed by DNA polymerization and specific nuclease digestion of undesired double- and single-stranded regions. Illustratively provided are DNA sequences useful in the microbial expression of bovine prolactin and other valuable polypeptides such as avian growth hormone.Type: GrantFiled: December 1, 1982Date of Patent: May 19, 1987Assignee: AmgenInventor: Lawrence M.
