Patent number: 11021738Abstract: A method of maintaining contiguity in chromosomal DNA following treatment with a tagmentase. Conditions are selected such that the tagmentase does not release from the DNA, and thus forms a bridge linking DNA segments that have the same relationship (haplotype) as occurred in the genomic DNA. Thus the tagmentase step can occur in bulk (before partitions are formed). The resulting tagmentase-bridged DNA segments can be added to partitions maintaining the bridged segments until they are introduced into different partitions. Once in partitions, the contiguous DNA segments can be barcoded with a partition-specific barcode, thereby allowing for later identification of contiguous DNA after sequencing in bulk (after partitions contents are merged).Type: GrantFiled: December 19, 2017Date of Patent: June 1, 2021Assignee: Bio-Rad Laboratories, Inc.Inventors: Ronald Lebofsky, Jeremy Agresti

Patent number: 10977665Abstract: Systems and methods for provenance tracking and/or identification of a product using genetic material are claimed. In various embodiments, genetic material such as plasmids may be incorporated into and/or otherwise persistently associated with a product. The genetic material may be encoded with, among other things, information that may uniquely identify the product, provide details relating to the origins of the product, the handling, distribution, and/or chain of custody of the product, intellectual property rights and/or other rights associated with the product, and/or the like. By extracting and analyzing the genetic material from the product, information encoded in the genetic material may be obtained by an interested party.Type: GrantFiled: February 11, 2020Date of Patent: April 13, 2021Assignee: Intertrust Technologies CorporationInventor: Jarl Nilsson
