Gram-Level Production of Four mAbs with Custom Purification Workflows

 

 

Four monoclonal antibodies were generated using customized purification workflows, each completed within 3-4 weeks. All the final molecules demonstrated high yields (3-110 g), high purity (>98%) and low endotoxin levels (<0.2 EU/mg).

 

60-L Monoclonal Antibody Production Completed in 4 Weeks

 

 

In 4 weeks, 80 grams of the target monoclonal antibodies were produced from 60 L CHO cells. The final product achieved 99% purity confirmed by SEC-HPLC and LC-MS analysis, with an endotoxin level below 0.02 EU/mg.
