Publication number: 20250066763Abstract: 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.Type: ApplicationFiled: October 22, 2024Publication date: February 27, 2025Applicant: New England Biolabs, Inc.Inventors: Ming-Qun Xu, Yi Fang, Aihua Zhang, Luo Sun

Patent number: 6858775Abstract: A new type of transgene system is disclosed which allows efficient protein expression in a target host such as a plant, but avoids the undesirable result of the migration of the transgene into related host system and/or to the environment via the pollen. The methods described herein may also be applied to the expression of virtually any protein of interest (e.g. a toxic protein) in eukaryotic (yeast, insect, mammalian cells, etc.) and prokaryotic (E. coli, etc.) organisms.Type: GrantFiled: May 23, 2000Date of Patent: February 22, 2005Assignee: New England Biolabs, Inc.Inventors: Ming-Qun Xu, Thomas C.

Publication number: 20040198958Abstract: Improved methods for purification, detection or characterization of molecules have been described in embodiments of the present invention. The improved methods rely on the ability to create a carrier reagent which is capable of (i) binding to a matrix either specifically or non-specifically; and (ii) forming a covalent linkage with any ligand having a nucleophilic group or a thioester as a result of a simple reaction which does not require a variety of chemical reagents or sophisticated chemistry. The covalent linkage between the carrier and the ligand relies on the chemical reaction between a thioester and a nucleophilic group. The carrier should either contain a reactive thioester which if it is a protein should be at the C-terminal end of the protein or a reactive nucleophilic group which if it is a protein should be at the N-terminal end and should preferably be a cysteine or selenocysteine.Type: ApplicationFiled: December 11, 2003Publication date: October 7, 2004Inventors: Ming-qun Xu, Inca Ghosh, Luo Sun, Thomas C.
