  • Patent number: 5837878
    Abstract: Boron compound complexing reagents, boron compound complexes, and methods of synthesizing these reagents and complexes are disclosed. These reagents and complexes include those shown in General Formula CIII, General Formula CIV, and General Formula CVI. In one embodiment, the reagents of General Formula CIII may be used to produce, after condensation with a bioactive species (BAS), the reagent of General Formula CIV. The reagent of General Formula CIV may be used to form a complex with a boron compound, such as a complex shown in General Formula CVI.
    Type: Grant
    Filed: August 5, 1996
    Date of Patent: November 17, 1998
    Assignee: Prolinx, Inc.
    Inventors: Mark L. Stolowitz, Robert J. Kaiser, Kevin P. Lund
  • Patent number: 5831045
    Abstract: Modified nucleotides and polynucleotides which are useful in hybridization assays for the detection of target genes are provided. The modified polynucleotides contain at least one boronic acid moiety which is attached to a nucleotide base in a position which does not interfere with the hydrogen bonding capabilities of that base during duplex formation. The modified polynucleotides are typically formed from naturally occurring nucleotides and one or more modified nucleotides.
    Type: Grant
    Filed: April 11, 1997
    Date of Patent: November 3, 1998
    Assignee: Porlinx, Incorporated
    Inventors: Mark L. Stolowitz, Robert J. Kaiser
  • Patent number: 5830711
    Abstract: The present invention relates to the cloning of the gene of a thermophilic DNA ligase, from Thermus aquaticus strain HB8, and the use of this ligase for the detection of specific sequences of nucleotides in a variety of nucleic acid samples, and more particularly in those samples containing a DNA sequence characterized by a difference in the nucleic acid sequence from a standard sequence including single nucleic acid base pair changes, deletions, insertions or translocations.
    Type: Grant

  • Patent number: 5494810
    Abstract: The present invention relates to the cloning of the gene of a thermophilic DNA ligase, from Thermus aquaticus strain HB8, and the use of this ligase in a ligase chain reaction (LCR) assay for the detection of specific sequences of nucleotides in a variety of nucleic acid samples, and more particularly in those samples containing a DNA sequence characterized by a difference in the nucleic acid sequence from a standard sequence including single nucleic acid base pair changes, deletions, insertions or translocations.

  • Patent number: 5118802
    Abstract: The invention consists of compounds and methods for the synthesis of oligonucleotides which contain one or more free aliphatic amino groups attached to the sugar moieties of the nucleoside subunits. The synthetic method is versatile and general, permitting amino groups to be selectively placed at any position on oligonucleotides of any composition or length which is attainable by current DNA synthetic methods. Fluorescent dyes or other detectable moieties may be covalently attached to the amino groups to yield the corresponding modified oligonucleotide.
