An Example of Evaluation of protein A Multicolumn Processes for the Capture of Large-Volume, High Concentration Bioreactors, Based on BioSC® Predict Optimization Software

The present paper provides some recent data regarding the optimization of BioSC® processes using three commercially available protein A resins, based on the BioSC® Predict software. A rapid description of the first steps to develop a multi-column process guided by simulation is provided to avoid generating unrealistic conclusions. Other approaches could however be applied depending on the objectives targeted. Examples of multicolumn systems based on three commercially available protein A resins are also provided, for the purification of a 15,000-L fed-batch bioreactor at 2, 5 and 10 g/L of monoclonal antibody, respectively. These systems will be compared to a reference batch process.
