  • Patent number: 10240196
    Abstract: Provided herein, among other things, are a variety of methods for transposase-mediated tagging and amplification of short DNA fragments, e.g., between about 150 bp and 1.5 Kb in length. In some aspects, the method includes tagging the DNA fragments with a first primer sequence using barcoded transposases followed by a primer extension reaction to introduce a second primer sequence, e.g., using random or gene-specific primers. Kits for performing this method are also provided.

  • Publication number: 20120003713
    Abstract: The invention provides novel extracts, proteins, and complexes that improve the polymerization activity of nucleic acid polymerases. Included within the aspects of the invention are methods for identifying compositions with a polymerase enhancing activity, methods for purifying and using these compositions, and specific extracts, proteins, and complexes that function to enhance polymerase activity. As an example, specifically described is nucleotide and amino acid sequence information for a Pyrococcus furiosus PEF (P45), which was used to produce a recombinant PEF.
