Abstract: Methods for preparing highly purified AAV vector formulations are provided. The highly pure AAV formulations described herein are superior for clinical use.

Abstract: In accordance with the present invention, a method for increasing the yield of rLV vector particles comprising a trans gene encoding a therapeutic protein or fragment thereof is disclosed. In one approach, cells are transfected with plasmids encoding the necessary components for rLV production using a calcium chloride transfection mix at pH 7.1 wherein the calcium chloride and plasmids form a complex which is added to the cells at a constant speed. The cells are then incubated for a suitable time period wherein virus particle media is collected at least twice during the incubation period and stored in a cold storage unit, thereby reducing virus inactivation.

Abstract: The present invention provides methods for making and using chimeric AAV particles having broad tissue tropism. The AAV particles may be used to deliver nucleic acid sequences encoding a desired protein wherein infection by chimeric AAV particles provides means to transduce cells with the nucleic acid sequences. Such gene transduction results in production of the desired protein in a cell, and thus establishes or restores the activity of the protein in the cell. The present invention also provides pharmaceutical compositions comprising such chimeric AAV particles for use in the therapeutic treatment of patients.
