Committed to the Highest Quality Standards
Quality is not just a department; it's the foundation of our entire operation. Our robust Quality Management System (QMS) is woven into every stage of the project lifecycle. This system ensures that every project, from initial research-grade material to full-scale cGMP production, adheres to the strictest, phase-appropriate industry standards and regulatory expectations.
We operate state-of-the-art cGMP facilities designed to be fully compliant with global regulatory guidelines, including those from the FDA, EMA, and NMPA. Our dedicated Quality Assurance (QA) and Quality Control (QC) teams provide continuous, independent oversight throughout the entire manufacturing process. This vigilance guarantees the purity, safety, efficacy, and consistency of your product batch after batch. Furthermore, we provide comprehensive documentation support, preparing audit-ready data packages essential for your regulatory (IND, BLA, NDA) submissions.

Frequently Asked Questions
Find quick answers to common inquiries about our CDMO services, processes, and technical capabilities.
What CDMO services do you offer for recombinant proteins and enzymes?
We provide a comprehensive, one-stop solution. This begins with gene synthesis and codon optimization, moving to expression vector construction and stable cell line or strain development. We then cover full upstream (media/feed optimization, bioreactor scale-up) and downstream (purification, TFF, analytics) process development. Finally, we manage cGMP manufacturing for clinical or commercial supply, including formulation, aseptic fill/finish, and full regulatory documentation support.
Which expression system is right for my molecule?
The best system depends on your molecule's characteristics and goals. For simpler, non-glycosylated proteins where speed and cost are key, *E. coli* is excellent. For proteins requiring basic eukaryotic folding or secretion, *Pichia* yeast is a powerful, high-yield choice. For complex enzymes or proteins needing post-translational modifications (PTMs) closer to, but not identical to, human, our insect (BEVS) platform is ideal. For therapeutic proteins requiring human-like PTMs (e.g., glycosylation), our mammalian (CHO, HEK293) systems are the cGMP standard.
How do you ensure regulatory compliance?
Compliance is central to our operation. Our Quality Management System (QMS) is built to be cGMP compliant and aligns with global regulatory guidelines (ICH, FDA, EMA). We ensure this through rigorous, independent QA oversight, comprehensive validation of processes and analytical methods, strict data integrity controls, and meticulous documentation (e.g., Master Batch Records, CoAs, full traceability). Our facilities are audit-ready for both clients and regulatory agencies.
How do you handle tech transfer if I have an existing process?
We have a dedicated, phased tech transfer process. It begins with a gap analysis of your existing data package (cell line, process descriptions, analytical methods). Our team then works with yours to transfer materials and methods, performing initial verification runs. We optimize as needed (e.g., for new raw materials or scale) and perform engineering runs before proceeding to full cGMP validation. Clear communication and a joint project team are key to ensuring the transfer is seamless and successful.
