    • A method for mass-producing a recombinant adeno-associated virus sero type 2(rAAV2) vector and a method for purifying the rAAV2 vector are provided to increase production efficiency and infection efficiency of the rAAV2 vector, save production cost, and minimize immuno-reaction caused by contaminated proteins by improving the purification degree, thereby being useful for producing a gene therapeutic agent for clinical test. A method for mass-producing a recombinant adeno-associated virus sero type 2(rAAV2) vector comprises the steps of: (a) transforming a 293T cell(ATCC CRL-11268) using a pAAV vector including a target gene, an AAV rep-cap plasmid DNA including an AAV2 replication(rep) sequence and an AAV2 capside(cap) sequence, and an adenovirus helper plasmid; (b) culturing the transformed 293T cell for 2-3 days; and (c) lysing the cultured cell line to obtain an rAAV2 vector. A method for purifying the rAAV2 vector comprises the steps of: (a) transforming a cell with the pAAV vector including the target gene, the AAV rep-cap plasmid DNA including the AAV2 replication(rep) sequence and the AAV2 capside(cap) sequence, and the adenovirus helper plasmid; (b) culturing the transformed cell; (c) after lysing the cultured cell, subjecting the lysed cell to CsCl density gradient centrifugation to isolate the rAAV2 vector; and (d) subjecting the isolated rAAV2 vector to centrifugal filtration using Centricon. Further, the target gene is one or more selected from VEGFR-1(vascular endothelial growth factor receptor-1), cDNA, VEGFR-2 cDNA, antisense VEGF-A cDNA, antisense VEGF-B cDNA and antisense VEGF-C cDNA.
