🧬 AAV Virus Production at Scale
Complete Solutions for Maximum Titers: Multi-Layer Systems, Premium Sera & Single-Use Technology
⚠️ The Challenges of AAV Production
Scaling AAV vector production is complex: Low titers, high costs, inconsistent batch quality, and poor scalability hold back your gene therapy programs.
📉 Low Vector Yields
Titers of 1E10-2E11 vg/mL in crude harvest aren't enough. Clinical doses require 100-10,000-fold concentration – with massive purification challenges.
💰 Exploding Manufacturing Costs
200-500L bioreactors must be concentrated to 100-200mL final product. Costs for cGMP plasmid DNA and reagents are prohibitively high.
⚖️ Limited Scalability
Adherent HEK293 systems with roller bottles or cell stacks aren't scalable. Each batch requires hundreds of flasks and massive manual labor.
📦 Batch-to-Batch Variability
Inconsistent plasmid uptake, varying empty-capsid rates, and fluctuating cell health lead to unpredictable results.
🧫 Contamination Risks
Open systems, multiple handling steps, and long production times dramatically increase contamination risk – especially in clinical production.
⏱️ Time-Intensive Processes
From cell expansion through transfection to harvest: weeks per batch. Long campaigns delay clinical programs by months.
