John T. Niemiec 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).

  • Amplification using modified primers
    Patent number: 6794142
    Abstract: The present invention provides modified primers for use in the amplification of a nucleic acid sequence. Amplifications carried out using the modified primers result in less template-independent non-specific product (primer dimer) compared to amplifications carried out using unmodified primers.
    Type: Grant
    Filed: October 24, 2001
    Date of Patent: September 21, 2004
    Assignee: Roche Molecular Systems, Inc.
    Inventors: Walter J. Laird, John T. Niemiec

  • Primers and probes for detecting Pneumocystis carinii
    Patent number: 5593836
    Abstract: Primers and probes can be used to detect nucleic acid from human strains of Pneumocystis carinii in a sample. The nucleotide sequence of a region of the 18S ribosomal RNA gene of a strain of P. carinii derived from humans is provided. The primers amplify regions of the 18S ribosomal RNA gene and hybridize to regions containing variability among strains. Probes hybridize to a regions within the amplified region that contain variability among strains.
