Mammalian Cell Culture Process Development | Abzena

Mammalian Manufacturing Process Development

  • Abzena’s runs purification development activities in parallel with upstream and assay development activities to minimise time scales
  • Aim to improve yield with optimisation of each step in the upsteam and downstream process

Upstream Process Development

Abzena develops a practical, robust, reproducible and scalable cell culture process suitable for clinical production. Abzena performs a series of bench studies examining growth and productivity performance under set basic parameters such as nutrient analysis, pH and dO2 in order to optimise the production procedure.

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 test are completed Abzena produces a development cell bank ready for 5 – 20 L scale fermentations to assess cell line stability (with regard to protein productivity and quality) through:

  • Growth curve analysis
  • Seeding density (split ratio/defined)
  • Extended passage – also suitable for larger scale cGMP production
  • Derivation of expansion format
  • Cell/product performance data (cell count and viability, WB and ELISA)
  • Seed pool generation

Downsteam Process Development

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

During the programme to develop and scale-up the purification process the studies are based upon established data and include, as a minimum, analysis of:

  • Recoveries
  • Impurity removal
  • Product stability
  • Process consistency

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.
