Challenges in scaling up AAV-based gene therapy manufacturing
The current manufacturing process for AAV products already uses unit operations that were largely adapted from mAb bioprocessing (Figure 4). As these processes evolve further for AAV, more consideration will be needed to make the developability and USD stress conditions more suitable to mimic the process stresses experienced by AAV.
Quartz Manufacturing Process Step by Step
The manufacturing process of quartz stone begins with selection of quality raw material for quartz stone production. These raw materials are finely selected, hereafter 90 % quartz aggregates and 10% polyester resin and other additives are crushed and blended. Using a vacuum and vibration process the mixture is compacted into slabs.
