Such molecules and/or compounds or combinations of such molecules and/or compounds can also be bound through recombination to various structures or supports according to the invention.Type: ApplicationFiled: February 28, 2014Publication date: October 2, 2014Applicant: LIFE TECHNOLOGIES CORPORATIONInventors: Michael BRASCH, Devon Byrd, David Cheo, James Hartley, Gary Temple

Patent number: 8846402Abstract: A method for engineering and utilizing large DNA vectors to target, via homologous recombination, and modify, in any desirable fashion, endogenous genes and chromosomal loci in eukaryotic cells. These large DNA targeting vectors for eukaryotic cells, termed LTVECs, are derived from fragments of cloned genomic DNA larger than those typically used by other approaches intended to perform homologous targeting in eukaryotic cells. Also provided is a rapid and convenient method of detecting eukaryotic cells in which the LTVEC has correctly targeted and modified the desired endogenous gene(s) or chromosomal locus (loci) as well as the use of these cells to generate organisms bearing the genetic modification.Type: GrantFiled: December 19, 2012Date of Patent: September 30, 2014Assignee: Regeneron Pharmaceuticals, Inc.Inventors: Aris N. Economides, Andrew J. Murphy, David M. Valenzuela, David Frendewey, George D. Yancopoulos

Patent number: 8846387Abstract: This invention provides methods for obtaining targeted gene modification in vertebrate cells using parvoviral vectors, including adeno-associated virus (AAV). The parvoviral vectors used in the methods of the invention are capable of targeting a specific genetic modification to a preselected target locus in a cellular genome by homologous pairing.Type: GrantFiled: May 24, 2011Date of Patent: September 30, 2014Assignee: The University of WashingtonInventors: David W.
