Testa Challenge 2024

Testa Challenge 2024 

The Testa Challenge 2024 bioproduction workflow - specifications 

 
A start to finish bioprocess producing monoclonal antibodies, aimed at generating intermediate materials for antibody drug conjugate (ADC) applications. 

 

Process outline: 

  • Monoclonal antibody (mAb) production in CHO cells through a fed-batch process in a single-use stirred-tank 50L bioreactor 
  • Clarification of CHO culture using depth filtration 
  • Isolation and purification of the produced mAb with an affinity chromatography step followed by an additional polishing step to reduce impurities 
  • The quality of the produced, purified monoclonal antibody (mAb) will be assessed using various analytical techniques
