Peptide-Enhanced Transfections

View page
US Patent:
6376248, Apr 23, 2002
Filed:
Mar 16, 1998
Appl. No.:
09/039780
Inventors:
Jianqing Lan - Germantown MD
PoJen Shih - Columbia MD
Joel A. Jessee - Mt. Airy MD
Kevin P. Schifferli - Germantown MD
Gulilat Gebeyehu - Silver Spring MD
Valentina C. Ciccarone - Gaithersburg MD
Krista L. Evans - Germantown MD
Assignee:
Life Technologies, Inc. - Rockville MD
International Classification:
C12N 1588
US Classification:
435458, 4353201, 4352351, 536 231
Abstract:
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.
