Patent number: 11905556Abstract: The invention generally relates to sequencing library preparation methods. In certain embodiments, two or more template nucleic acids are joined together by a linking molecule, such as a PEG derivative. Identical copies of a nucleic acid fragment or both strands of a duplex fragment may be linked together. The linked nucleic acids are amplified, creating linked amplicons. Emulsion PCR with linked primers creates linked template nucleic acids for seeding sequencing clusters and errors can be readily identified by their presence on only one of the linked fragments.Type: GrantFiled: February 18, 2021Date of Patent: February 20, 2024Assignee: NCAN Genomics, Inc.Inventors: Joel Pel, Andrea Marziali

Patent number: 11905557Abstract: According to various embodiments described herein, a microfluidics-chip based purification device and system for Sanger-sequencing reactions is provided. The device and system allow for the introduction into a sequencing system of a cartridge containing purification technologies specific to the sequencing contaminants or sequencing method where the simplified purification solution of a cartridge allows automation of the sample purification process, reduced consumption of purification reagents, and consistency in sampling by reducing the sampling errors and artifacts. These various embodiments therefore solve the need for a microfluidics-chip-based, Sanger-sequencing reaction purification system for CE devices. The microfluidic chips described can be used as a PCR chip by reorganizing the on-chip reagents, reaction wells and work flow steps.Type: GrantFiled: March 5, 2021Date of Patent: February 20, 2024Assignee: LIFE TECHNOLOGIES CORPORATIONInventors: Swati Goyal, Achim Karger, Peter Ma, S.
