Cell Line Development

Mycenax develops and establishes high-quality cell lines for various host cell and product types. We are the experts for all cell line development activities from vector construction to generating cell banks for GMP manufacturing in accordance with ICH and global regulatory requirements. We also support early-stage material generation for proof-of-concept studies or preclinical development programs.

Mycenax carries out cell line development as a stand-alone service or as an integrated end-to-end development solution including process development and GMP manufacturing. In addition, you can combine this service with Mycenax’ proprietary cell line development platforms to shorten the development time.


Host Cell Lines

  • Cell & Gene Therapy
    • Natural killer cells

Our Capabilities

  • Stable cell line generation from vector construction to cell bank generation
  • GMP master cell bank and working cell bank generation
  • Understanding of business and science-driven objectives for the choice of expression platform, e.g. IP status and licensing terms
  • Application of established, commercially proven expression platforms in order to streamline subsequent process development activities
  • Compliance with ICH and global regulatory requirements
  • Gene and codon optimization of expression plasmids
  • Clone selection based on product yield and quality, cell line stability and cell culture performance
  • Verification of critical product quality attributes by extensive analytical testing during initial steps of the clone selection process
Process Development

Mycenax uses streamlined and robust technology platforms for process development to move your projects forward fast to GMP manufacturing. Manufacturing processes are developed using quality by design principles and design of experiments approaches in accordance with ICH and global regulatory requirements. After process development, product quality is determined by state-of-the-art analytical methods and high-throughput equipment.

Mycenax offers a complete solution for process development including development of production cell lines, upstream process development, downstream process development, process scale-up, formulation development, and analytical methods.

With our experience gained over more than a decade and from various product types, our team solves all technical problems in order to ensure the success of your project.
