- Culturing a genetically engineered host cell line;
- Introducing a nucleic acid construct into said host cell;
- Cultivating the host cell under specific conditions to produce the viral vector;
- Harvesting and purifying the viral vector.
Claim 2:
The method of claim 1, wherein the host cell line is selected from HEK293, PER.C6, or a modified cell line with enhanced viral production capacity.
Claim 3:
The cultivation conditions include at least one of the following parameters:
- Specific temperature ranges (e.g., 32°C–37°C);
- Controlled pH levels;
- Optimized nutrient supply.
Claim 4:
The nucleic acid construct comprises genetic elements designed to increase viral vector stability and infectivity.
Claim 5:
The method yields a viral titer exceeding a specified threshold (e.g., 1×10^10 infectious units per mL) under the described conditions.
Claim 6:
