AAV production process using serum free 293 suspension cells (200L)
The pilot process development strategy and parameters for the small batches successfully guide the 200L scale-up AAV production process using serum-free 293 suspension cells.
Actual AAV production up to 7.3E+16 vg (total yield) for 200L production system
T空壳率可低<5%
分析型超高速离心AUC
降低HCD
