Mammalian Cell Culture Process Development | Abzena

Process Development

Upstream utilising ambr® technology

Abzena utilise the latest ambr® technology so different media can be screened against temperature shifts, impeller speeds, CO and pH to produce a more robust process and understand important process parameters increasing the speed of upstream development. From 15-2000L the reactors are geometrically similar, so data obtained is comparable from lab to plant.

Bench-scale fermentations are designed by Abzena to identify the upper and lower limits for each parameter (according to current ICH guidelines) that will be suitable as a laboratory scale process for use in later phase development for retrospective validation of the upstream process.

Once bench-scale tests are completed Abzena produces a development cell bank ready for fermentations to assess cell line stability for protein productivity and quality).


Abzena produces a robust, consistent and scalable process with the goals of maintaining yield, purity and quality of the drug substance.

Optimisation of the purification process includes:

  • Clarification
  • Capture, Ion Exchange and SEC Chromatography
  • Ultrafiltration/diafiltration
  • Viral reduction

Abzena’s purification development activities are performed in parallel with upstream and assay development activities.
