POROS CaptureSelect AAVX Affinity Resin is engineered to address the high selectivity and capacity requirements for large-scale downstream purification of a broad range of naturally occurring and synthetic adeno-associated virus (AAV) serotypes used for gene therapy applications. POROS CaptureSelect AAVX resin has demonstrated binding reactivity towards a set of AAV serotypes that includes AAV1 to AAV8, and AAVrh10 as well as synthetic serotypes.

Features of POROS CaptureSelect AAVX resin include:

• One-step AAV purification from crude material with high purity and yield
• High specificity and capacity, maximizing yield by significantly reducing process steps
• Superior capacity maintained at high flow rates
• Excellent scalability and easier handling and packing due to rigid polymeric bead
• Non-animal derived

POROS CaptureSelect AAVX Affinity Resin enables a robust, fast, and platformable purification process for wide-ranging AAV serotypes with excellent purity and yield obtained in one step. This resin comes with complete technical and regulatory support.

Free of animal components

CaptureSelect products contain affinity ligands based on recombinant single-domain antibody fragments (VHH) created by a proprietary technology. The VHH affinity ligand is a 12 to 15 kDa fragment comprising the three complementarity-determining regions (CDRs) that form the antigen-binding domain, efficiently produced in the yeast Saccharomyces cerevisiae by a production process free of any animal components (Animal Origin-Free).
