Downstream Processing
The separation and purification steps of biotech processing, including chromatography and filtration. Vaccine and monoclonal antibody (MAb) manufacturing are also found here.

Developing a MAb Aggregate Removal Step by High Throughput Process Development

April 1, 2010

HTPD allows rapid screening of chromatographic parameters.

The Challenge of Defining the Higher Order Structure of Biopharmaceutical Products

March 5, 2010

Characterizing the higher order structure (HOS) of protein drugs increases manufacturers' understanding of stability and batch-to-batch variability, and may make it possible to link variants or aggregates to safety and efficacy. Yet at the January 24 CMC Strategy Forum in Washington, DC, regulators expressed concern that methods to characterize the three-dimensional structure of proteins are not routinely applied to biotechnology products.
