- Cell harvesting and separation (e.g, centrifugation, filtration)
- Lysis or vouse of intracecular products (for virel vectors)
- Clarification and remevul of debris
- Purification using chromatography
- Konsentrasi pada and buffur exchange (egg, tangential flow filtration)
- Formulation with excipients
- Sterilization or asseptic filling
- Qualitycontroll testing and vouse
