We can provide optimal in vitro transcription vector designs, large-scale IVT mRNA manufacturing, and LNP encapsulation followed by thorough quality control tailored to a wide range of research and clinical needs.
Cell Banking
We can generate GMP-grade Master Cell Banks (MCBs) and Working Cell Banks (WCBs) for E. coli, mammalian cells and insect cells, derived either from our in-house validated cell lines or customer-provided cell lines.
We can do manual or automated aseptic filling of the DS/DP into glass vials (0.25 to 2 ml) or cryo bags. We have the capacity to complete >3000 vials per batch.
Regulatory Support

We work closely with our customers to provide regulatory support at each critical milestone of their drug development process. These include:

  • Consultation for regulatory strategy
  • Support for IND-enabling documentation
  • Preparing CMC documentation for clinical trial and BLA filing
  • On-site audit by regulatory authorities
  • Addressing manufacturing questions from HAs
  • QP support for European customers
Technology Transfer
We can provide technology transfer with best practices including detailed bill of materials, well-documented production process, and fully qualified analytical methods used in the manufacturing of the gene therapy vector.

Our comprehensive quality system is embedded in every aspect of our GMP manufacturing process that spans facilities, supplies, production, fill/finish, storage, in-process and release QC, and personnel. Our company culture places great emphasis on quality, innovation, continuous improvement, and “white-glove” customer service. As such, we can consistently meet and exceed customer expectations. We also strive to achieve rapid turnaround and affordable prices while maintaining high quality and full regulatory compliance.
