Stable Cell Line Development


Stable cell line is the best solution, not only for manufacturing therapeutic and diagnostic proteins, but also for application in drug screenings, as well as pharmacological and toxicological studies. ExonBio offers a comprehensive solution in the creation of stable mammalian cell line, which can be used to produce recombinant proteins and antibodies.

  • Stability: You want to develop a stable cell line because it is "stable", in expressing the target protein. However, not all stable cell lines are equally "stable". After several passages, some stable cell lines may become unstable, with their expression diminishing slowly. This is a very common problem for many stable cell lines. To resolve this critical issue, ExonBio has developed a system that makes the cell lines more stable than ever. We have found that, even after 25 generations, their expression level is comparable to the earlier generations.
  • High expression: If you need to develop a cell line high in protein yield, we provide the best system to create a stable cell line with capability of expressing high amount of intracellular or secreted of the targeted protein.
  • Fast: High productivity stable clone approximately in 12 weeks.

What we offer:
  • Comprehansive Services: From gene synthesis, gene cloning, gene variant construction to stable cell line development and protein expression and purification,
  • Convenient Service: With either the client's own documented cell line or commercially available cell lines, our expression vectors have been tested and shown to integrate efficiently into the cell chromosome of major cell lines. This lead to a stable cell line with maximum expression yield.
  • Competitive Services: Our high expression system will have a better chance of in getting a stable cell line with high expression yields of your target gene.

ExonBio is committed to a competitive, comprehensive and rapid solutions for stable and high yield Cell Line Development and Protein expression and purification.
