Downstream Processing: Improving Productivity in Downstream Processing

BioPharm International
Volume 19, Issue 11


Improvements in feedstream titers translate into the need for improvements in downstream processing productivity. A multiprong approach has enabled downstream process scientists to achieve the necessary productivity. The proven strategies include the use of platform technologies consisting of second-generation resins with increased capacity and velocity, and enhanced stability to harsh cleaning and sanitization conditions.


The Polymer Chain Reaction (PCR) is covered by patents owned by Roche Molecular Systems and F Hoffmann-La Roche. A license to use the PCR process for certain research and development activities accompanies the purchase of certain reagents from licensed suppliers.
