Purification Sourcing Center

Biologic purification is a critical series of downstream steps required to capture a target biomolecule and remove host cell related impurities, process related impurities, and product related impurities.

Those steps include protein extraction or isolation, purification, and polishing. The purification process generally exploits differences in protein size, biological activity, physicochemical properties, and binding affinity to produce specific, pure proteins. Whether at bench-scale or in a high-volume commercial production environment, the purification of biologic pharmaceutical products is complex and expensive, typically representing upwards of 50 percent of a therapeutic antibody’s downstream manufacturing cost, and often causing production bottlenecks. BioProcess Online offers a host of timely resources to help you manage the cost—and overcome the complexity—of the downstream purification process.
