Application Of Immobilized Enzymes For Nanopore Library Construction

US Patent:
2022029, Sep 22, 2022
Filed:
May 31, 2022
Appl. No.:
17/828574
Inventors:
- Ipswich MA, US
Yi Fang - Ipswich MA, US
Aihua Zhang - Hamilton MA, US
Luo Sun - Hamilton MA, US
Assignee:
New England Biolabs, Inc. - Ipswich MA
International Classification:
C12N 15/10
C12Q 1/6806
C12Q 1/6869
Abstract:
The present disclosure relates, according to some embodiments, to methods for preparing a library for sequencing. For example, a method may comprise (a) in a coupled reaction, (i) contacting a population of nucleic acid fragments with a tailing enzyme to produce tailed fragments, and (ii) ligating to the tailed fragments a sequencing adapter with a ligase to produce adapter-tagged fragments; and/or separating adapter-tagged fragments from the tailing enzyme and the ligase to produce separated adapter-tagged fragments and, optionally, separated tailing enzyme and/or separated ligase. In some embodiments, a tailing enzyme and/or a ligase used in library preparation may be immobilized enzymes.

Abstract:
The subject technology receives first metadata corresponding to a set of micro-partitions. The subject technology stores a first data structure and a second data structure in storage as a first file and a second file, first data structure including the first metadata and a second data structure including second metadata, the first metadata corresponding to a set of micro-partitions, the second metadata for a grouping of the first metadata, the second data structure including information associating the second metadata to the first metadata. The subject technology stores third metadata for a table, the third metadata comprising information about data stored in a micro-partition of the table.

System And Method For Non-Disruptive In-Memory Certificate Management

US Patent:
2021009, Apr 1, 2021
Filed:
Sep 30, 2019
Appl. No.:
16/587750
Inventors:
- Hopkinton MA, US
Yi Fang - Sharon MA, US
Jingyan Zhao - Harvard MA, US
International Classification:
G06F 16/23
G06F 21/64
Abstract:
A method, computer program product, and computer system for maintaining, by a computing device, a plurality of certificates in a credential store using a distributed data source. A certificate of the plurality of certificates may be loaded in an in-memory location from the distributed data source upon startup. A change in at least one certificate of the plurality of certificates may be detected in the distributed data source. The change in the at least one certificate may be loaded from the distributed data source to the in-memory location without requiring a restart of the computing device.
