Our Promise

Authentic Cells in Every Vial

Commitment to Quality

As a premier cell line bank, we guarantee that our cells are rigorously tested for:

  • Mycoplasma via a colorimetric assay and a PCR-based method
  • Identity via STR-analysis*
  • Viral contaminants
  • Bacteria and Fungi

We are dedicated to providing cells that retain their original genetic composition and phenotypic traits, enhancing the reliability of your experimental outcomes. Our documentation of each cell passage underscores our commitment to traceability and reproducibility in research. We empower researchers with the confidence that comes from knowing the complete health of their cell cultures.

Quality Journey

In 2012, Cytion, previously known as CLS Cell Lines Service GmbH, implemented a quality management system compliant with ISO 9001:2008 standards. This system has undergone continuous enhancements and regular updates to uphold its effectiveness. By 2013, process development was fully incorporated into our quality management practices, further strengthening our commitment to excellence. In pursuit of maintaining the highest quality standards for our customers, Cytion transitioned to the updated ISO 9001:2015 standard in February 2018, ensuring our processes align with the latest industry benchmarks.
