  • Patent number: 6027883
    Abstract: A sample preparation procedure for mitochondrial (mt) DNA analysis is described. The present method for isolating mtDNA uses sedimentation techniques for separating erythrocytes from lymphocytes and platelets (crude buffy coat fraction), followed by DNA extraction from the crude buffy coat fraction by boiling in water. This approach improves the yield of mutant DNA, enhancing the sensitivity of subsequent mutation interrogation techniques and allowing for meaningful statistical treatment of the degree of heteroplasmy within the mitochondrial DNA.

    Date of Patent: February 22, 2000
    Assignee: Mitokor
    Inventors: Corinna Herrnstadt, Soumitra Ghosh, Eoin D. Fahy, Robert E. Davis
  • Patent number: 5976798
    Abstract: The present invention relates to methods of detecting genetic mutations in mitochondrial cytochrome oxidase c genes that segregate with Alzheimer's Disease and methods for determining the amount of heteroplasmy of mitochondrial nucleic acid. The invention provides methods for detecting such mutations, as a diagnostic for Alzheimer's Disease, either before or after the onset of clinical symptoms.

  • Patent number: 5474895
    Abstract: Methods for the detection of nucleic acid using sandwich hybridization are provided. The target nucleic acids are captured by hybridization with oligonucleotides covalently attached to polystyrene solid supports to form complexes which are then hybridized to detection oligonucleotides to facilitate the analysis of the target nucleic acid sequences.

  • Patent number: 5210203
    Abstract: Nucleic acid hybridization probes are provided which comprise an N.sup.4 -(substituted amino)cytosine moiety, wherein the substituted amino group comprises a tag moiety, whereby the probe is detected. Methods of preparing probes of the invention, intermediates used in such methods, and methods of using the probes of the invention in hybridization assays are also provided. Typical tag moieties employed with the probes of the invention are biotinyl, aminothiadiazole and fluorescein derivatives, connected to N.sup.4 -amino groups of modified cytosines of the probe through linker moieties. Probes tagged with biotin are typically detected by binding to the biotinyl moieties, through a streptavidin or avidin molecule, a reporter group which includes streptavidin or avidin and then detecting a signal due to the reporter group.

  • Patent number: 5130446
    Abstract: Fluorescent linker moieties are provided which comprise a fluorescent compound such as fluorescein attached to a linker moiety such that a functional group of the linker is available for attachment to an affinity molecule such as a nucleic acid which has an N.sup.4 (substituted amino) cytosine moiety. Probes tagged with fluorescent derivatives such as fluorescein, tetramethyrhodamine or tetraethylrhodamine may be detected by fluorescence spectroscopic methods.

  • Patent number: 4780405
    Abstract: Nucleic acid hybridization probes are provided which comprise nucleoside bases or terminal nucleotide phosphates chemically linked to aromatic sulfonamide inhibitors of carbonic anhydrase. Methods of preparing probes of the invention, intermediates used in such methods, and methods of using the probes of the invention in hybridization assays are also provided. A probe of the invention is detected by binding to it a reporter group, such as a homopolymer or heteropolymer of enzymes, which includes a carbonic anhydrase which binds to the inhibitor linked to the probe, and then detecting the bound reporter group, as by production of a fluorescent or colored product in a reaction catalyzed by an enzyme component of the reporter group. Also provided are enzyme immunoassays wherein detection of antibody is by a process which comprises a chemical reaction catalyzed by a carbonic anhydrase.
