Patent number: 10184122Abstract: 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).Type: GrantFiled: July 21, 2015Date of Patent: January 22, 2019Assignee: Epicentre Technologies CorporationInventors: Haiying Li Grunenwald, Nicholas Caruccio, Jerome Jendrisak, Gary Dahl
