Interferon production with multitray culture system on a large scale.

Area of Science:

• Biotechnology
• Cell Culture Technology
• Bioprocess Engineering

Background:

• Traditional cell culture methods face challenges in scalability and cost-efficiency for biopharmaceutical production.
• Large-scale interferon (IFN) production requires robust and reproducible culture systems.

Purpose of the Study:

• To develop and evaluate a novel multitray culture system for large-scale cell culture and IFN production.
• To assess the system's efficiency, reusability, and cost-effectiveness compared to existing methods.

Main Methods:

• Design of a multitray culture apparatus with stacked trays and a reservoir.
• Utilizing nontoxic, washable, and autoclavable materials for system components.
• Cultivation of anchorage-dependent cells, including mouse L cells and human fibroblasts.

Main Results:

• The multitray system demonstrated highly efficient production of mouse IFN (MuIFN-alpha and MuIFN-beta) and human beta interferon (HuIFN-beta).
• Achieved significantly higher yields compared to roller bottle, bulk culture vessel, and microcarrier systems.
• The system's materials allow for repetitive use, contributing to low running costs.

Conclusions:

• The developed multitray culture system is a viable and efficient solution for large-scale cell culture and interferon production.
• Offers a cost-effective and reusable alternative to conventional bioprocessing systems.
• Facilitates high-yield biopharmaceutical manufacturing, particularly for interferons.
