We are deeply committed to achieve your milestones, timelines and target titers.
Your cell line development timeline
From DNA to IND
Your gene is integrated into transcriptionally active DNA, which guarantees high productivity, high cell line stability (>95%) and high comparability between stable pools and clonally derived cell lines.
- Extensive media and feed screening to identify optimal production conditions
- Cell line stability study is included
- Development of scalable upstream and downstream processes and tech transfer (optional)
- Use of Design of Experiments (DoE) for process optimization
- State-of-the-art FDA and EMA compliant cloning procedures for documented proof of clonality
- Support for assay development and analytics
- Cell line development reports which support clinical trials and market authorization (IND, CTA/BLA, MAA)
- Full freedom in choice of media and feeds, including proprietary media
- Licensing opportunities for the CLD platform are available.
