The platform process for MAb is:
- Depth filtration
- Pro A + low pH inactivation + filtration
- Cation or Anion exchange chromatography
- Virus filtration
- Ultra-filtration
- Use this process to remove HCP/HCDNA/Aggregation and control charge variant.
- During process development, each unit operation CPP will be developed with design space.
- Linear scale up from bench to 10, 50 and 250L related scale, the process description will be transferred into batch records for pilot scale.
- All the CQAs and recovery will be monitored during scale up to dial in the TPP.
