Platform Technology for Developing Purification Processes

The future of therapeutic MAbs lies in the development of economically feasible downstream processes.

Downstream Processing: Platform Technology for Developing Purification Processes
March 1, 2007

To shorten time to market for new therapeutic proteins, new and fast methods, such as high throughput screening, are needed to speed up downstream processing. The platform technology discussed in this article includes a structural approach that can be used as a general procedure to purify therapeutic proteins. The approach starts with ligand screening and selection-on-a-chip, with the Surface Enhanced Laser Desorption Ionization–Time of Flight (SELDI–TOF) mass spectrometer system. Next, resin screening and supplier selection are performed using robotics, followed by scouting studies under dynamic conditions to select the best resin. Finally, optimization studies of critical parameters are carried out with statistical design approaches (design of experiments). A few examples are presented to explain the platform approach for purification development in more detail.
