Patents by Inventor Norman Arnheim

Norman Arnheim has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4800159
    Abstract: The present invention is directed to a process for amplifying and detecting any target nucleic acid sequence contained in a nucleic acid or mixture thereof. The process comprises treating separate complementary strands of the nucleic acid with a molar excess of two oligonucleotide primers, extending the primers to form complementary primer extension products which act as templates for synthesizing the desired nucleic acid sequence, and detecting the sequence so amplified. The steps of the reaction may be carried out stepwise or simultaneously and can be repeated as often as desired.In addition, a specific nucleic acid sequence may be cloned into a vector by using primers to amplify the sequence, which contain restriction sites on their non-complementary ends, and a nucleic acid fragment may be prepared from an existing shorter fragment using the amplification process.
    Type: Grant
    Filed: December 17, 1986
    Date of Patent: January 24, 1989
    Assignee: Cetus Corporation
    Inventors: Kary B. Mullis, Henry A. Erlich, Norman Arnheim, Glenn T. Horn, Randall K. Saiki, Stephen J. Scharf
  • Patent number: 4798787
    Abstract: Antibodies exhibit specificity toward single amino acid differences between proteins. These antibodies may be produced by synthesizing a peptide of the appropriate amino acid sequence contained in the protein, immunizing a host with the peptide, and extracting sera from the host to obtain the antibodies. The antibodies and the desired protein are then immunoprecipitated under conditions of partial denaturation to expose the epitope of the protein. The antibodies may be used for diagnostic or therapeutic purposes.
    Type: Grant

    Assignee: Cetus Corporation
    Inventors: Francis P. McCormick, Gail L. Wong, Robin Clark, Norman Arnheim, Danute E. Nitecki
