Area of Science:

  • Biotechnology
  • Bioprocessing
  • Cell Line Development

Background:

  • Cell line development (CLD) is critical for therapeutic biologic manufacturing, primarily using Chinese hamster ovary (CHO) cells.
  • CHO cell characteristics like random integration and plasticity lead to significant diversity in productivity, growth, and quality, necessitating extensive screening.
  • Conventional CLD is laborious and resource-intensive due to the need to screen numerous cell pools and clones.

Purpose of the Study:

  • To develop and validate a novel deep-well plate (DWP) enabled high throughput (DEHT) platform for accelerated cell line development.
  • To assess the suitability of 24-well DWPs for key CLD steps, including cell passaging, imaging, expansion, and fed-batch production.
  • To demonstrate the DEHT platform's efficiency in screening more cultures compared to traditional methods.

Main Methods:

  • Implementation of a DEHT CLD platform utilizing 24-well DWPs, liquid handlers, and automation.
  • Validation of 24DWP suitability by assessing well-to-well and plate-to-plate variability and cross-contamination.
  • Comparison of growth, production, and product quality in 24DWP cultures versus conventional shake flask cultures.

Main Results:

  • The DEHT platform successfully integrated key CLD steps within a 24DWP format.
  • Minimal variability and absence of cross-contamination were confirmed in 24DWP cultures.
  • 24DWP cultures demonstrated comparable growth, production, and product quality to shake flask cultures.
  • The DEHT platform enables screening of five times more cultures than conventional CLD.

Conclusions:

  • The DEHT platform offers a robust and efficient solution for cell line development in biologics manufacturing.
  • This automated approach significantly reduces the time and resources required for identifying high-producing cell lines.
  • The DEHT platform represents a substantial advancement in optimizing the early stages of biopharmaceutical production.
