AVIPure® AAV Affinity Resins
AVIPure® AAV Affinity Resins provide capture step purification of adeno-associated virus (AAV) 2, 5, 8, and 9 vectors with potential alkaline clean-in-place regeneration for improved process economics. A 50 µm cross-linked agarose matrix bead ensures compatibility with standard bioprocess columns and flow rates.
AAV process cost reduction
- ~20% lower resin cost/L
- > 20 cycle re-use, NaOH stable
- High binding capacity, yield, purity
Pre-packed or loose resin
- Available now: AAV2, AAV5, AAV8, AAV9
- Available pre-packed in OPUS® Columns
High performance at a lower price point
AVIPure® AAV 2, 5, 8, and 9 Affinity Resins meet or exceed the performance metrics of resins developed on alternative platforms with the additional benefit of robust alkaline stability. Affinity resins offer the ability to simplify downstream processing. NaOH stable affinity resins simplify processes and dramatically improve overall process economics.
- Maintain high host cell protein (HCP) clearance and residual DNA clearance levels after 20 cycles
- Across life of the resin using 0.1 to 0.5 M NaOH for routine cleaning and sanitization
- High dynamic binding capacity even at short residence time enables use with pre-concentrated feed or direct capture:
- >2 x 1014 vp/mLresin at 1 minute residence time
- >7 x 1014 vp/mLresin at 4 minute residence time
Retain performance with NaOH CIP regeneration
Overlay of every fifth cycle from a single AVIPure® AAV2 column used in a 31-cycle study demonstrating robust chromatographic performance after cleaning in place with NaOH. Total NaOH exposure time at final cycle was 15 hours.
Consistently high yield and clearance of host cell protein (HCP) and host cell DNA (hcDNA) were achieved across 31 cycles on a single AVIPure® AAV2 column. Yield was measured using commercially available AAV2 Progen ELISA kits, HCP was measured by HCP ELISA, and hcDNA was measured by Picogreen assay. Average yield was 105%, average 4.0 log reduction of HCP to 977 ppm, and average 2.8 log reduction of hcDNA to 400 ppm.
Bind with 2-minute residence time, Clear more HCP and DNA
Bind, wash and elute direct capture of AAV cell culture feed (not concentrated) stream using AVIPure® AAV2 Resin.
A 2 -minute residence time enabled elimination of an existing pre-concentration step. Product was eluted in 50 mM glycine, 150 mM NaCl, 0.01% P188, pH 3 with 85% recovery.
AVIPure® AAV2 Resin and a competing AAV affinity resin were run under identical conditions. The eluted product was analyzed for purity by SDS-PAGE, HCP and residual DNA.
AVIPure AAV2 Resin and a competing AAV affinity resin were run under identical conditions (2 minute residence time) with the eluted product analyzed for purity by SDS-PAGE, HCP and residual DNA. AVIPure AAV2 Resin delivered purified product with 7-fold lower residual HCP, 1.5X lower residual DNA and fewer impurity proteins by SDS-PAGE.
