  • Patent number: 11021689
    Abstract: The invention describes a method for obtaining purified recombinant Adeno-Associated Virus particles (rAAV), comprising the steps of: a) performing a depth filtration of a starting material previously obtained from cells producing rAAV particles, the said starting material being selected in a group comprising a cell lysate and a culture supernatant, whereby a rAAV-containing clarified composition is provided; b) submitting the rAAV-containing clarified composition to an affinity purification step, whereby a first rAAV enriched composition is provided; c) submitting the first rAAV enriched composition at least once to: c1) a step of anion-exchange chromatography on a chromatographic support wherein elution is performed by using a salt gradient, preferably a linear salt gradient, and wherein the rAAV-containing fraction is collected, whereby a second rAAV enriched composition is provided; or c2) a step of density gradient centrifugation, wherein the rAAV-containing fraction is collected, whereby a second rAAV e
