Patent number: 8932860Abstract: The invention provides methods and nucleic acid constructs that may be used to modify a nucleic acid of interest at a target locus within the genome of a host. In some aspects, the invention contemplates producing in vivo a gene targeting substrate (GTS), which may be comprised of both DNA and RNA components. The gene targeting substrate may comprise a gene targeting nucleotide sequence (GTNS), which is homologous to the target locus, but comprises a sequence modification compared to the target locus. The gene targeting substrate may be produced by reverse transcription of a gene targeting message RNA (gtmRNA). The gene targeting message RNA may be folded for self-priming for reverse transcription by a reverse transcriptase. The gene targeting message RNA may in turn be the product of transcription of a gene targeting construct (GTC) encoding the gene targeting message RNA.Type: GrantFiled: August 22, 2008Date of Patent: January 13, 2015Assignee: Her Majesty in Right of Canada as Represented by the Minister of Agriculture and Agri-Food CanadaInventors: Kevin L.

Patent number: 7850745Abstract: Methods for recovery of concentrates of lubricating compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or enrichment protocols that increase the concentration of high lubricity compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components. The high boiling point compounds that are the residues of distillation, however, can contribute significant lubricity and may be used widely in lubricant applications or added to petroleum fuels to decrease friction.Type: GrantFiled: December 1, 2005Date of Patent: December 14, 2010Assignee: Her Majesty in Right of Canada as represented by the Minister of Agriculture and Agri-Food CanadaInventors: Martin J.
