  "abstract": "The present invention relates to the detection of specific nucleic acid sequences after an amplification process, or directly without amplification. In particular, the invention provides for the automation of the amplification and detection process, the amplification and detection of one or more specific nucleic acid sequences, the use of internal controls, reduced potential for contamination caused by the manual manipulation of reagents, and improved reagent compositions to better control assay performance and provide for further protection against contamination.",
  "claims": [
    "1. A device for the automated detection of at least two target nucleic acid sequences, said device comprising a pipette-like device having an internal and external surface and an internal cavity defined by said internal surface, wherein said internal surface is coated with at least two capture nucleic acid sequences which bind to said target nucleic acid sequences to form hybridization complexes, and wherein said target nucleic acids are discretely detected in said device.",
    "2. A device as in claim 1 wherein said capture nucleic acids are coated on said internal surface of said device in at least two distinct zones.",
    "3. The device as claimed in claim 2 wherein said zones are spatially separated.",
    "4. The device as in claim 3 wherein said zones are coated homogenously.",
    "5. The device as in claim 2 wherein said zones are coated homogenously.",
    "6. A device as in claim 1 wherein said capture nucleic acids are coated in said internal surface of said device in a single homogenous zone.",
    "7. The device as in claim 1 wherein said capture nucleic acids are coated on said internal surface of said device in two distinct zones.",
    "8. The device as claimed in claim 7 wherein said zones are spatially separated.",
    "9. The device as in claims 1 wherein the internal cavity is coated with a first capture nucleic acid sequence and a second capture nucleic acid sequence, said first capture nucleic acid coated in a first zone and said second capture nucleic acid coated in a second zone of said internal cavity, wherein said first or second capture sequences hybridize to complementary target nucleic acid sequences to form hybridization complexes in said first or second zone.",
    "10. The device as claimed in claim 9 wherein said first and second zones are spatially separated.",
    "11. The device as in claim 1 wherein said target nucleic acids are detected for results selected from the group consisting of truncated gene expression, specific allele and specific spliced genes."

  "description_excerpt": "This application is a divisional application of U.S. patent application Ser. No. 08/850,171, filed May 2, 1997, now abandoned.\n\nThe present invention relates to the detection of specific nucleic acid sequences in a target test sample.\n\nIn particular, the present invention relates to the automated detection of specific nucleic acid sequences which are either unamplified or amplified nucleic acid sequences (amplicons).\n\nIn addition, the present invention relates to the use of automated amplification, methods and compositions for monitoring successful amplification, improved methods for reducing the chance for contamination, and the use of unified reaction buffers and unit dose aliquots of reaction components for amplification.\n\nFinally, the present invention also relates to unique constructs and methods for the conventional or automated detection of one, or more than one different nucleic acid sequences in a single assay.\n\nThe development of techniques for the manipulation of nucleic acids, the amplification of such nucleic acids when necessary, and the subsequent detection of specific sequences of nucleic acids or amplicons has generated extremely sensitive and nucleic acid sequence specific assays for the diagnosis of disease and/or identification of pathogenic organisms in a test sample.\n\nAmplification of Nucleic Acids\n\nWhen necessary, enzymatic amplification of nucleic acid sequences will enhance the ability to detect such nucleic acid sequences.",
