POROS™ CaptureSelect™ AAV9 high performance affinity resin is engineered to address the high selectivity and capacity requirements for the purification of viral vectors used for gene therapy applications and is specifically intended for the purification of adeno-associated virus type 9 (AAV9).
Features of POROS CaptureSelect AAV9 resin include: • One-step AAV9 purification from crude material with high purity and yield • High specificity and capacity, which helps reduce the process volume significantly for subsequent steps and maximizes yield • Low operating back pressure and linear pressure versus flow responses driving flexible scalability • Superior capacity maintained at high flow rates • Rigid polymeric bead with covalent surface chemistry for easier handling and packing, with superior physical and chemical stability enabling a more robust downstream purification process • Non-animal derived—the ligand is a 13-kDa single-domain fragment that comprises the 3 CDRs that form the antigen-binding domain and is efficiently produced by the yeast Saccharomyces cerevisiae in a production process free of animal components.
POROS CaptureSelect AAV9 affinity resin specifically binds AAV9 and enables a robust, fast, and efficient purification process with excellent purity and yield obtained in one step. The use of this affinity resin will enable significant improvement to downstream processing by reducing the purification steps and maximizing productivity, for scalability and processing consistency.
