Genetic Stability Test

Genetic stability testing is required to demonstrate that the genetic sequence of an expression construct is stable throughout the production life cycle to ensure the quality and consistency of the product and production process. Next Generation Sequencing (NGS) is now recognized as one of the most powerful and reliable tools for full genome sequencing. Using NGS for the cell line characterization purpose will allow you to run one study rather than performing multiple assays to achieve the same results.

Overall solution

CD BioSciences applies the following methods to determine the genetic stability of recombinant production cell lines and to characterize plasmid products:

  • Restriction endonuclease mapping
  • Southern blotting
  • Northern blotting
  • Copy number determination by qPCR
  • DNA and RNA sequencing
  • Plasmid sequencing
  • Retention of recombinant construct

CD BioSciences provide next-generation sequencing (NGS) services, which can also be used for genetic stability testing. Our partnership can accelerate your drug development by providing fast and comprehensive testing.
