Abstract: The present invention provides lipid aggregate compositions having at least two cationic lipids in combination with one or optionally more than one non-cationic lipids for the in vitro and/or in vivo delivery of biologically active molecules including nucleic acids, specifically DNA and RNA, and proteins into cells and tissues. Methods are also provided that use the compounds of the present invention to deliver biologically active molecules, into cells and tissues to facilitate the expression of target proteins therein. In some non-limiting embodiments, the subject lipid aggregate compositions can be used to deliver nucleic acid molecules to facilitate the expression of proteins involved in cellular reprogramming and genome editing applications.

Abstract: Provided herein are, inter alia, compositions and methods useful for the in vivo delivery of bioactive agents (e.g., therapeutic or diagnostic agents). The compositions provided herein include cationic lipids, helper lipids and a biostability enhancing agent, which together form a lipid aggregate with the bioactive agent and allow for the systemic delivery of the bioactive agent to, for example, lung tissue without the requirement for biomolecular targeting.

Abstract: There are provided for herein novel amine-containing transfection compounds and methods for making and using same. The compounds are generally obtained by reacting a primary amine with an unsaturated compound. Transfection complexes made using the amine-containing transfection compounds in combination with additional compounds to encapsulate biologically active agents such as nucleic acids are also provided for herein. Methods of using the transfection complexes for the in vivo or in vitro delivery of biologically active agents are also described. The transfection complexes of the present invention are highly potent, thereby allowing effective modulation of a biological activity at relatively low doses compared to analogous transfection compounds known in the art.

Abstract: The present invention is directed to non-naturally occurring peptides containing a membrane-penetrating amino acid sequence and further at least one polycationic moiety or peptide sequence. The peptides are suitable for use in delivery a cargo to the interior of a cell. Suitable cargo includes nucleic acid molecules (including DNA, RNA or PNA), polypeptides, or other biologically active molecules. The present invention is further directed to transfection complexes containing the non-naturally occurring peptides of the present invention in non-covalent association with at least one cationic lipid and a cargo to be delivered to the interior of a cell. The invention further relates to methods for the preparation and use of the non-naturally occurring peptides for the formation of transfection complexes and the delivery of a cargo to the interior of a cell in culture, an animal or a human. The invention also relates to compositions and kits useful for transfecting cells.

Abstract: A lentiviral vector production system comprises (a) a lentiviral culture supplement to control cell growth, (b) a transfection reagent comprising DHDMS, DOPE, and cholesterol to increase transfection efficiency, (c) a lentiviral production enhancer comprising sodium propionate, sodium butyrate, and caffeine to boost lentiviral production, wherein the lentiviral vector production system is serum-free. A method of lentiviral vector production comprises using the lentiviral production system. Another method for lentiviral vector production comprises (a) culturing eukaryotic cells in a serum-free medium, (b) providing a lentiviral culture supplement to control cell growth, (c) transfecting the cells with a lentiviral vector using a transfection reagent comprising DHDMS, DOPE, and cholesterol to increase transfection efficiency, and (d) providing a lentiviral production using a lentiviral production enhancer comprising sodium propionate, sodium butyrate capable of boosting lentiviral production.
