  • Method for diagnosis of lyme disease
    Patent number: 5912117
    Abstract: Methods and reagents are provided for amplifying and detecting target nucleic acid sequences in a sample suspected of containing Borrelia spirochetes using the polymerase chain reaction (PCR) process. The PCR process employs primers and probes which are derived from the 16S ribosomal RNA gene of Borrelia burgdorferi and Borrelia hermsii.
    Type: Grant
    Filed: October 9, 1992
    Date of Patent: June 15, 1999
    Assignee: Roche Molecular Systems, Inc.
    Inventors: Deborah E. Dodge, Thomas J. White
  • Oligonucleotide primers for amplifying HCV nucleic acid
    Patent number: 5837442
    Abstract: The present invention provides improved primers for the polymerase chain reaction (PCR) amplification of a nucleic acid sequence from hepatitis C virus (HCV). The primers and amplification methods of the invention enable the detection of HCV with greatly increased sensitivity.
    Type: Grant
    Filed: October 28, 1996
    Date of Patent: November 17, 1998
    Assignee: Roche Molecular Systems, Inc.
    Inventor: Sue Yen Tsang
  • Nucleotide sequence variation in the ABO glycosyltransferase gene
    Patent number: 5763184
    Abstract: Methods and reagents for determining an individual's genotype at the ABO locus with respect to newly discovered polymorphisms, which facilitates typing tissue for determinign individual identity and has application in the field of forensic science.
    Type: Grant
    Filed: December 11, 1996
    Date of Patent: June 9, 1998
    Assignee: Roche Molecular Systems, Inc.
    Inventors: Rebecca Lynne Reynolds, Gabriele Annemarie Zangenberg
  • Primes and probes for the amplification and detection of aids associated nucleic acids
    Patent number: 5386022
    Abstract: The presence or absence of a nucleic acid sequence associated with AIDS in a sample containing one or more nucleic acids and suspected of containing such sequence can be detected by amplifying the sequence using primers to form extension products as templates and detecting the amplified product if it is present. This may be accomplished by adding a labeled hybridization probe to the amplified product either free in solution or after immobilization on a solid support. Exemplary primers and probes for amplifying and detecting AIDS virus are provided.
    Type: Grant
    Filed: July 16, 1993
    Date of Patent: January 31, 1995
    Assignee: Hoffman-La Roche Inc.
    Inventors: John J. Sninsky, Shirley Y. Kwok, David Mack, Henry A. Erlich, Kary B. Mullis
