Patents by Inventor George D. Sorenson

George D. Sorenson 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).

  • Detection of soluble gene sequences in biological fluids
    Patent number: 6020124
    Abstract: Methods are provided for detecting and quantitating gene sequences, such as mutated genes and oncogenes, in biological fluids. The fluid sample (e.g., plasma, serum, urine, etc.) is obtained, deproteinized and the DNA present in the sample is extracted. The DNA is then amplified using an amplification procedure, such as PCR or LCR, to amplify the mutated gene sequence. In one embodiment, the DNA is contacted with a peptide nucleic acid prior to or during the amplification procedure.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: February 1, 2000
    Assignee: Trustees of Dartmouth College
    Inventor: George D. Sorenson
  • Detection of allele - specific mutagens
    Patent number: 5496699
    Abstract: Methods are provided for detecting and quantitating gene sequences, such as mutated genes and oncogenes, in biological fluids. The fluid sample (e.g., plasma, serum, urine, etc.) is obtained, deproteinized and the DNA present in the sample is extracted. Following denaturation of the DNA, an amplification procedure, such as PCR or LCR, is conducted to amplify the mutated gene sequence.
