GMP Production Cell Line Development

Production cell line development is one of the most challenging tasks for any drug developer or service provider, especially if subsequent Good Manufacturing Practice (GMP) compliance fulfilling all relevant pharmaceutical guideline specifications is a requirement. Our GMP production cell line development service combines the use of powerful cGMP-compliant technology platforms and our longstanding cell line development experience as a partner for companies in the biotech and pharmaceutical industry. It results in a highly productive GMP-compliant cell lines suitable for use from the R&D phase up to successful introduction of high quality therapeutic antibodies and proteins to the health market. Full regulatory-compliant process control is ensured.


High producer cell line & cGMP-compliant technology platforms

Our cGMP-compliant production cell line development process is based on the proven and industry leading CHO-K1 or Freedom ExpiCHO-S™ systems for the manufacturing of antibody and non-antibody proteins. Both systems have a high scale-up stability from small scale research to cGMP manufacturing levels.

After completion of the production of cell line development process, your resulting high quality research cell bank (RCB) can be transferred to a CDMO (Contract Development and Manufacturing Organization) of your choice for further process development, optimization and high level production. The generated cell line can be easily upgraded for commercial use after the R&D phase by a one-time license fee payment (royalty-free).

“Our GMP-compliant production cell line development project was performed professionally and qualitatively. We thank trenzyme for the good collaboration and hope for future projects.”

GMP-compliant Production Cell Line FAQs

Which parental cell lines do you use?

We use Celonic’s CHOvolution® CHO-K1 and Thermofisher’s Freedom ExpiCHO-S™ as parental cell lines. Other cell lines on request.

What is the final productivity of the cell line after cell line development?

As a high standard productivity, we can reach up to 3g/l for mABs after cell line development. After process development, it can reach > 8 g/l.

Which type of license do you offer?

Within the cell line generation at trenzyme, a R&D license is already included and has not to be purchased. For any commercial application later on, a commercial license is needed.
