Improving DNA Removal from Bioprocess Purification Processes
Many new biological drug products produced using recombinant DNA technology, such as monoclonal antibodies, are produced in cell culture. Because therapeutic proteins such as monoclonal antibodies are produced in cell culture, impurities can result from the host cells, or cell substrates. By 3M Purification Inc.

Continuous Harvesting Of Extra-Cellular Proteins From Mammalian Cell Cultures Utilizing Small-Scale Perfusion
The use of a small-scale cell culture system not only maximizes the production of valuable protein but also avoids the high capital cost associated with system scale-up. Continuous harvesting can provide significant improvements in protein yields when compared to those of typical batch operations.
