Viral Vector Production and Purification
Producing high-purity, therapeutically viable viral vectors is a complex challenge where yields inherently decrease at every stage of development. To overcome these bottlenecks, Beckman Coulter Life Sciences introduces a holistic, integrated workflow solution designed to maximize recovery and ensure consistency from initial cell culture to final analytical characterization.
By seamlessly bridging upstream production with robust downstream purification—utilizing automated liquid handling, high-performance centrifugation, and density gradient ultracentrifugation—this workflow enables researchers to efficiently isolate pure, fully intact viral capsids from empty or partially packaged variants.
Key Workflow Pillars
1. Upstream Production & Culture
- Cell Culture & Transfection: Automated plasmid handling and cell monitoring using the Biomek i-Series Automated Liquid Handler and VI-CELL BLU/MetaFLEX analyzers to optimize transfection efficiency and monitor animal cell culture viability inside the bioreactor.
2. Downstream Processing & Purification
- Clarification: Efficient separation of viral particles from cell culture media utilizing Avanti JXN-Series High-Performance Centrifuges.
- Density Gradient Ultracentrifugation: High-resolution separation of empty, partially assembled, and fully assembled intact vectors with complete genomes using OptiMATE Gradient Makers, Reagents, and Optima X-Series Ultracentrifuges.
- Polishing & Sterile Filtering: Final buffer exchange and concentration to achieve the target formulation.
3. Analytical Characterization
- Quality Control & Quantification: Precise batch characterization and exact quantification of empty vs. full viral capsids using the Optima AUC (Analytical Ultracentrifuge) to ensure safety, efficacy, and consistency.
