Publication number: 20110035836Abstract: The present invention provides a novel method for the transduction and/or transfection of plant cells. Cell-penetrating peptides (CPPs) have been successfully employed as nanocarriers to deliver proteins and oligonucleotides to single plant cell microspores as well as multi-cellular zygotic embryos. The efficiency of CPP internalization and further delivery of a macromolecular cargo comprising a protein and/or an oligonucleotide can be enhanced by permeabilization of the zygotic embryos.Type: ApplicationFiled: June 9, 2008Publication date: February 10, 2011Applicant: AGRICULTURE AND AGRI-FOOD CANADAInventors: Francois Eudes, Archana Chugh

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.
