  • Patent number: 10100348
    Abstract: The present invention provides a simple and rapid method for preparing purified transposase complexes that are highly suited for fragmenting DNA. The method includes forming transposase complexes with oligonucleotide adapters in cell lysate, then purifying the complexes from the other substance in the cell lysate. Purification is accomplished using a specific binding pair, in which one member of the pair is bound to an oligonucleotide adapter of the complex and the other member of the pair is bound to a solid substrate. The bound complexes can be immediately used in DNA fragmentation reactions to produce solid substrate-bound DNA fragments, which can be used for any number of purposes, including as templates for amplification and sequencing.

  • Patent number: 9005935
    Abstract: The present invention provides new compositions for transposase-mediated fragmenting and tagging DNA targets. The invention relates to the surprising discovery that use of manganese ions (Mn2+) in transposase reactions improves the transposase reaction. It also relates to the surprising discovery that Mg2+ ions can be used in a transposase reaction with wild-type and/or engineered transposases at levels much higher than previously thought. The invention provides for the use of naturally-occurring transposases in in vitro reactions, as well as improved schemes for cleaving, tagging, and amplifying target DNA.

  • Publication number: 20090298088
    Abstract: The present invention provides a detection reagent for detection of the presence of a substance of interest in a sample. The detection reagent comprises a binding portion, a linking portion, and a catalytic portion. The linking portion comprises a cleavage site for cleavage of the binding portion from the catalytic portion. According to the method, the detection reagent is caused to bind to the substance of interest. The bound reagent is then cleaved by breaking of a bond in the linking portion. Upon cleavage, the catalytic portion is removed from the binding reaction mixture and caused to catalyze a reaction that produces a detectable product.
