  • Patent number: 12043851
    Abstract: Disclosed are DNA polymerases having improved ability to incorporate methylated-dNTPs, relative to a corresponding, unmodified polymerase. The polymerases are useful in a variety of disclosed primer extension methods. Also disclosed are related compositions, including recombinant nucleic acids, vectors, and host cells, which are useful, e.g., for production of the DNA polymerases. Further disclosed are kits and reaction mixtures comprising the improved DNA polymerases as well as methods of primer extension using the improved DNA polymerases.

  • Patent number: 10150990
    Abstract: The present application provides polynucleotides comprising 5?-tails with sequence segments useful for the detection of target nucleic acid sequences, and methods for their use in detecting target nucleic acids. The polynucleotides are used to amplify a subsequence of a target nucleic acid in the presence of one or more ribonucleotides. The ribonucleotides are incorporated into amplification products at regular intervals complementary to the 5?-tail sequence segments. Cleavage of amplification products at the bond immediately 3? to incorporated ribonucleotides produces detectably distinct fragments indicative of the presence or absence of a target nucleic acid.

  • Patent number: 7745125
    Abstract: The present invention provides reaction mixtures that include blocked oligonucleotides comprising 2?-terminator nucleotides. The blocked oligonucleotides are rendered extendible when the 2?-terminator nucleotides are removed from the oligonucleotides, e.g., via pyrophosphorolysis. The reaction mixtures can be used in various nucleic acid polymerization and/or amplification assays, among many other applications. In addition to reaction mixtures, the invention also provides related methods and reaction mixtures.
