  • Patent number: 10184122
    Abstract: The present invention provides methods, compositions and kits for using a transposase and a transposon end for generating extensive fragmentation and 5?-tagging of double-stranded target DNA in vitro, then using a DNA polymerase for generating 5?- and 3?-tagged single-stranded DNA fragments without performing a PCR amplification reaction, wherein the first tag on the 5?-ends exhibits the sequence of the transferred transposon end and optionally, an additional arbitrary sequence, and the second tag on the 3?-ends exhibits a different sequence from the sequence exhibited by the first tag. The method is useful for generating 5?- and 3?-tagged DNA fragments for use in a variety of processes, including processes for metagenomic analysis of DNA in environmental samples, copy number variation (CNV) analysis of DNA, and comparative genomic sequencing (CGS), including massively parallel DNA sequencing (so-called “next generation sequencing).

  • Patent number: 9790540
    Abstract: The present innovation provides methods and kits that enable rapid and efficient dual end-tagging of RNA to prepare libraries for analysis by applications such as next-generation RNA sequencing, qPCR, microarray analysis, or cloning. The methods do not require time-consuming and inefficient gel-purification steps that are common to methods known in the art. In addition, the present invention provides methods and kits for rapid, high-throughput enzymatic preparation of 5?-activated, 3?-blocked DNA oligonucleotides from standard, single-stranded DNA oligonucleotides.
