Patent number: 9879243Abstract: The present invention is directed generally to cell culture media useful for introducing macromolecules and compounds (e.g., nucleic acid molecules) into cells (e.g., eukaryotic cells) in the presence of said media. Cells containing introduced materials can be further cultured in the media. In particular, the invention allows introduction of nucleic acid molecules (e.g., vectors) into cells (particularly eukaryotic cells) and expression of proteins encoded by the nucleic acid molecules in the cells. The invention obviates the need to change the cell culture medium each time a different procedure is performed with the cells (e.g., culturing cells vs. transfecting cells). The invention thus provides efficient and high throughput methods to transform/transfect culture and cells avoiding the need for multiple manipulations and transfers of cells during transfection and expression studies.Type: GrantFiled: August 15, 2013Date of Patent: January 30, 2018Assignee: LifeTechnologies CorporationInventors: Valentina C. Ciccarone, Dale Gruber, Shelly Bennett

Patent number: 8058068Abstract: The present invention provides compositions useful for transfecting eukaryotic cells comprising nucleic acid complexes with peptides, wherein the peptide is optionally covalently coupled to a nucleic acid-binding group, and cationic lipids or dendrimers as transfection agents. The invention also provides transfection compositions in which a peptide is covalently linked to the transfection agent (lipid, cationic lipid or dendrimer). Inclusion of peptides or modified-peptides in transfection compositions or covalent attachment of peptides to transfection agents results in enhanced transfection efficiency. Methods for the preparation of transfection compositions and methods of using these transfection compositions as intracellular delivery agents and extracellular targeting agents are also disclosed.Type: GrantFiled: July 23, 2002Date of Patent: November 15, 2011Assignee: Life Technologies CorporationInventors: Pamela Hawley-Nelson, Jianqing Lan, PoJen Shih, Joel A.

Publication number: 20030096414Abstract: The present invention is directed generally to cell culture media (particularly serum free, non animal derived, and/or chemically defined media) which are useful for introducing macromolecules and compounds (e.g., nucleic acid molecules) into cells (e.g., eukaryotic cells). According to the invention, such introduction can take place in the presence of said medium. Cells containing such introduced materials can then be cultured in the medium and the effect of the introduced materials on the cells can be measured or determined. In particular, the invention allows introduction of nucleic acid molecules (e.g., vectors) into cells (particularly eukaryotic cells) and expression of proteins encoded by the nucleic acid molecules in the cells. The invention obviates the need to change the cell culture medium each time a different procedure is performed with the cells (e.g., culturing cells vs. transfecting cells).Type: ApplicationFiled: March 26, 2002Publication date: May 22, 2003Applicant: Invitrogen CorporationInventors: Valentina C.

Publication number: 20030008399Abstract: The present invention describes cells and constructs for a regulated viral (e.g. alphavirus) expression system, where gene expression is controlled by controlling expression of replicases or nonstructural proteins and/or controlling the amount of such proteins introduced in a cell, which in turn regulates RNA replication and subsequently gene expression. Particularly, this system takes advantage of the high level expression of the alphavirus systems for recombinant protein production and allows for large scale applications without biosafety concerns.Type: ApplicationFiled: August 7, 2002Publication date: January 9, 2003Applicant: Invitrogen CorporationInventors: Joel A.
