    • 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: cl) 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 enriched composition is provided; d) submitting the second rAAV enriched composition to a step of tangential flow filtration, whereby purified recombinant Adeno-Associated Virus particles (rAAV) are provided.
    • 本发明描述了获得纯化的重组腺相关病毒颗粒(rAAV)的方法,包括以下步骤:a)对产生rAAV颗粒的细胞预先获得的起始材料进行深度过滤,所述起始材料选自组 包括细胞裂解物和培养上清液,由此提供含rAAV的澄清组合物; b)将含有rAAV的澄清组合物递送至亲和纯化步骤,由此提供富含第一rAAV的组合物; c)将第一rAAV富集的组合物至少提供一次至:cl)在色谱载体上的阴离子交换层析步骤,其中通过使用盐梯度,优选线性盐梯度进行洗脱,并且其中含rAAV的级分为 收集,从而提供第二种富含rAAV的组合物; 或c2)密度梯度离心的步骤,其中收集含rAAV的级分,由此提供第二rAAV富集组合物; d)将第二rAAV富集组合物提交到切向流过滤步骤,由此提供纯化的重组腺相关病毒颗粒(rAAV)。
