Digitalization: The Route to Biopharma 4.0
The strategy was designed to handle deviations in titer from 1 g/L to 7 g/L by selecting a pre-programmed set of methodologies designed as per the requirements. In another study, integrated process mo…

Updating Viral Clearance for New Biologic Modalities
“If viruses are similar in size to the pore size of the VRF membrane, the extent to which a filter can reduce virus titer depends on the flow conditions applied to the VRF. Interrupting flow can exace…

Improving mAb Manufacturing Productivity by Optimizing Buffer and Media Prep Process Flow
A typical monoclonal antibody (mAb) process may require 2000 L of a buffer and more than 100,000 L per batch based on titer and bioreactor volume (1, 2). As a result, the variety of buffer solutions u…

Improving Upstream Predictability
“We’ve consistently been seeing titers in the range of 4–6 g/L in [monoclonal antibody] mAb fed-batch processing within a chemically defined media environment. This environment, in turn, results in mo…

Development of Purification for Challenging Fc-Fusion Proteins
In response, titers for monoclonal antibodies (mAbs) and Fc-fusion proteins have significantly increased (1-5).
Particularly for Fc-fusion proteins, these improvements have resulted in a …
